As the seasons change, your pet’s routine may change with them. Cooler weather, shifting schedules and more time indoors can all mean it’s a good time to take stock of your pet’s ongoing health needs.

From medications and preventatives to allergy care and upcoming vet appointments, a little preparation now can help keep your pet’s care on track throughout the fall. 

Start by taking a look at your pet’s current medications. Are you getting close to a refill? Is anything set to run out in the next few weeks? If your pet takes medication regularly, checking your supply now can help you avoid a last-minute scramble.

It’s also a good time to make sure you’re following the dosing instructions provided by your veterinarian and that you know when your next refill is due. If anything about your pet’s medication has changed, reach out to your veterinary team before making adjustments.

Fall can bring changes in the environment that may affect pets with seasonal allergies. Ragweed and other outdoor allergens can linger into the fall, while leaves, mold and changes in indoor air can introduce new irritants.

If your pet is prone to allergies, keep an eye out for signs such as itching, licking, scratching, red or irritated skin, ear problems or changes in their usual behavior. If you notice symptoms returning or getting worse, talk with your veterinarian about whether your pet’s allergy care needs to be adjusted.

Keeping any prescribed allergy medications on hand can also make it easier to stay on top of your pet’s routine.

Fall is a good time to look ahead at your pet’s healthcare calendar. Check whether they have any upcoming appointments, vaccinations, lab work or medication monitoring scheduled.

If your pet has a chronic condition or takes ongoing medication, staying consistent with recommended checkups can help your veterinary team monitor their health and make changes to their care when needed.

You can also use this time to write down any questions or changes you’ve noticed since your pet’s last visit so you’re ready to bring them up at their next appointment.

Fall often means changes to the whole household’s schedule. 

, changing work schedules and shorter days can affect when your pet eats, exercises and takes their medications.

If your pet takes medication at a specific time each day, consider how your new routine might affect their schedule. A consistent routine can make it easier to remember medications and notice when something seems different with your pet.

One of the easiest ways to stay ahead of your pet’s health needs is to check your supplies before they become urgent. Take inventory of medications, preventatives and other essentials your pet uses regularly.

If you’re getting close to needing a refill, reach out to your vet or pharmacy rather than waiting until you’re down to the last dose. Planning ahead can give you more time to coordinate a prescription and get everything delivered.

And when you need a hand managing your pet’s prescriptions, we’re here to help. From coordinating with your veterinary team to delivering medications right to your door, we make it easier to keep your pet’s care moving along.

Your Pet’s Fall Health Checklist

As pets get older, it’s normal for their routines and abilities to change. They may not run quite as far, take longer to get up in the morning or spend more time napping. But while some changes are a normal part of aging, slowing down can also be a sign that your pet is experiencing pain.

The challenge is that dogs and cats often hide discomfort. Instead of crying out or limping, they may simply behave a little differently. Knowing what to look for can help you recognize changes sooner and give your veterinarian the information they need to determine what’s going on.

Pain can look different from pet to pet, and some of the most important signs can be subtle. Changes in your pet’s everyday routine, movement or personality may be worth paying attention to, especially when they are new or becoming more noticeable.

You may notice your pet having more difficulty getting up or lying down. They might move more slowly, hesitate before climbing stairs or stop jumping onto furniture they used to enjoy. A dog may lose interest in longer walks or playing fetch, while a cat may stop jumping onto a favorite perch or spending time in certain areas of the house.

Changes in activity are another potential clue. A pet who is uncomfortable may sleep more, seem reluctant to move around or tire more quickly during activities they once enjoyed.

Behavior can also change when a pet is experiencing discomfort. A normally social pet may become withdrawn or irritable, or they may seem less comfortable being touched or handled. Some pets may become restless, pace or have trouble settling into a comfortable position. 

It can be difficult to know whether your pet is simply getting older or experiencing a problem that needs attention. Aging itself is not a disease, and many senior pets continue to enjoy active, comfortable lives.

The most helpful thing you can do is pay attention to changes from your pet’s normal behavior.

For example, an older dog may naturally take more naps than they did when they were younger. But if they suddenly stop wanting to go on walks, struggle to climb stairs or seem uncomfortable getting up, it’s worth bringing those changes to your veterinarian.

The same applies to cats. A senior cat may sleep more, but suddenly avoiding the couch they used to jump onto or spending much more time hiding could indicate an underlying issue.

If you notice a new or persistent change in your pet’s behavior, movement, appetite or daily routine, it’s a good idea to talk with your veterinarian. Your veterinarian can evaluate your pet, look for potential underlying causes and determine whether pain management may be appropriate. 

Depending on the cause and your pet’s individual needs, treatment may involve medication, weight management, physical rehabilitation, environmental changes or other approaches.

You know your pet’s normal better than anyone. Paying attention to small changes can help you recognize when something may be wrong and give you an opportunity to involve your veterinarian early.

For pets who need ongoing pain management, staying consistent with their treatment plan is an important part of their care. Keeping medications on schedule and planning ahead for refills can make it easier to avoid interruptions.

, we can help make managing your pet’s medications more convenient with home delivery, refill support and coordination with your veterinary team. Because when your pet needs ongoing care, keeping their routine on track should be one less thing to worry about.

Is Your Pet Slowing Down or in Pain?

Pets tend to thrive on routine. Familiar patterns around meals, exercise, medication and time spent with you can help them know what to expect throughout the day.

A change in schedule does not necessarily mean your pet will have a hard time adjusting. However, sudden changes can sometimes lead to behaviors like restlessness, excessive vocalization or changes in eating and sleeping habits.

The goal is not to keep every day exactly the same. Instead, focus on keeping the most important parts of your pet's routine as consistent as possible.

If you know your schedule is going to change, start adjusting your pet's routine ahead of time when possible.

For example, if you'll need to leave for work earlier, gradually move your pet's morning feeding or walk earlier over several days. Small changes can be easier for your pet to adapt to than one sudden shift.

Even when your schedule changes, maintaining a few familiar routines can give your pet a sense of stability.

One routine that is especially important to maintain is your pet's medication schedule.

Whether your pet takes medication every day or on a specific schedule, giving it consistently can help you stay on track with their care. A busy morning or a change in who is home can make it easier to accidentally miss a dose.

Try connecting medication time to something you already do every day, such as your morning coffee, breakfast or your pet's evening meal. Keeping medication in a consistent, easy-to-remember place can also help.

Keeping up with medication is not just about remembering doses. It's also important to make sure you have enough medication on hand when you need it. 

 makes it easy to manage your pet's ongoing medications and keep their care moving with your routine.

A new work or school schedule may also mean your pet spends more time alone than they did during the summer.

If your pet is used to having someone around throughout the day, gradually increasing alone time can help them adjust. Before leaving, make sure they have access to fresh water and a comfortable place to rest. Depending on your pet, a favorite toy or enrichment activity can also help keep them occupied.

If your pet shows persistent signs of distress when left alone, talk with your veterinarian about ways to support them.

Most pets will adjust to a new schedule with time. Still, it's worth paying attention if you notice significant or lasting changes in their behavior, appetite, sleep, bathroom habits or energy level.

Your pet cannot tell you when something feels off, so changes in their normal routine can sometimes be an important clue. If you're concerned about a change, your veterinarian can help determine whether it's simply an adjustment to a new routine or something that needs attention.

A little preparation now can help you settle into your new routine while keeping your pet's care on track.

How to Help Your Pet Adjust to a New Schedule

Managing chronic dermatology cases isn't just about selecting the right treatment plan — it's about helping pet owners stick with it.

During Koala's recent sponsored webinar, "When the Itch Won't Quit: Cultivating Compliance in Your Derm Cases," board-certified veterinary dermatologist Dr. Julia E. Miller, DACVD shared practical strategies for improving long-term compliance through stronger communication and a whole-clinic approach to patient care.

Here are five key takeaways from the discussion.

1. Dermatology Compliance Starts with the Entire Veterinary Team

Successful dermatology cases don't rely on one conversation with the veterinarian. Every interaction, from the front desk to the exam room, helps shape client experience and understanding.

When client service representatives, technicians and doctors all reinforce the same message, pet parents receive consistent guidance throughout their visit. That consistency builds trust and makes long-term treatment plans easier to follow.

One of the biggest opportunities to improve compliance is during the initial appointment.

Helping pet parents understand that many allergic skin conditions require ongoing management, not just a one-time fix, creates realistic expectations from the beginning. When pet parents know what the journey looks like, they're more likely to stay engaged with treatment, 

Follow-up care is a critical part of managing chronic dermatology patients.

Rather than asking clients to remember to call later, pre-booking the recheck appointments before they leave the clinic helps keep treatment plans on track and creates natural opportunities to evaluate progress, adjust therapies and answer questions.

4. Prepare Pet Parents for Allergic Flares

Even with an effective treatment plan, flare-ups can happen.

Talking about this possibility before it occurs helps reduce frustration and uncertainty when symptoms return. Pet parents who understand what to expect are often better prepared to recognize changes, reach out appropriately and continue following the recommended plan instead of assuming treatment has failed.

Technicians play a vital role in educating pet parents, reinforcing recommendations and answering day-to-day questions.

Providing ongoing education and clinical resources helps create a knowledgeable, confident team that can deliver consistent messaging across every stage of the patient journey. The stronger the team's understanding, the stronger the client (and patient!) experience becomes.

Better Communication Leads to Better Outcomes

Dermatology cases often require months (or even years!) of partnership between veterinary teams and pet owners. Improving compliance isn't about having one perfect conversation; it's about creating a consistent experience at every touchpoint.

, we're proud to support continuing education that helps veterinary teams strengthen client relationships, improve adherence to treatment plans and ultimately deliver better outcomes for pets.

Thank you to Dr. Julia E. Miller and the 

 team for an engaging discussion and for sharing practical strategies that clinics can begin implementing today. Didn’t get a chance to tune in? 

Top Five Ways to Improve Compliance in Veterinary Dermatology

Finding a tick on your dog or cat can be an unsettling moment, but knowing exactly what to do next makes all the difference. While it’s natural to feel worried when you spot fleas or ticks, the key to protecting your pet lies in a steady hand and a clear plan. Whether your pet is a frequent trail hiker or a backyard explorer, knowing how to handle these parasites is an essential part of responsible pet ownership.

A common misconception among pet owners is that ticks are only a problem during warm spring and summer months. In reality, ticks are a year-round risk for dogs and cats, particularly in many parts of the United States where milder winters allow tick activity to continue. According to the 

Because ticks transmit a wide variety of disease agents to pets and people and are active throughout the year, tick control must be practiced consistently to protect the health of the pet and to prevent untreated pets from bringing ticks – which may then infest people - into the home.”

This ongoing exposure matters because ticks are capable of transmitting several serious tick-borne diseases in dogs. These infections are not always obvious immediately following the bite. 

The Centers for Disease Control and Prevention

 notes that symptoms of tick-borne illness may take 7 to 21 days to appear after a bite, possibly longer. This delay makes prevention especially important, since treatment is often most effective when started early.

Because of this incubation period, pets may go through what veterinarians sometimes refer to as a “silent infection window.” During this time, a dog or cat may appear completely normal while the infection is developing internally. By the time more noticeable clinical signs of tick-borne disease appear, the illness may already be well established and require more intensive treatment. This is why consistent year-round tick prevention for pets is far more effective than reacting after a bite occurs.

The CDC recommends checking your pets for ticks daily, especially after they spend time outdoors. Ticks prefer warm, hidden areas of the body where they can feed undisturbed. On dogs, pay close attention to the area in and around the ears, around the eyelids, under the collar, under the front legs, between the toes, between the back legs and around the tail. For cats, the same areas apply, though cats will often groom ticks off before you spot them, making prevention and veterinary-recommended repellents especially important.

Ticks crawling on or biting a pet can be hard to spot, especially for breeds with long and dark fur. Take your time and use your fingertips to feel through the coat rather than relying on sight alone.

If you find a tick on your pet, the priority is to remove the feeding tick as soon as possible. Because the risk of pathogen transmission increases the longer a tick remains attached to its host, acting quickly is the most effective way to protect your pet’s bloodstream from infection. A tick’s anatomy is designed for a secure hold, featuring a one-piece body equipped with harpoon-like barbs on the mouthparts, supported by crab-like legs and a sticky, cement-like secretion that anchors it firmly in place.

 provides clear, vet-informed guidance on how to remove a tick from your dog using fine-point tweezers or a tick removal hook. They advise spreading your dog's fur, grasping the tick as close to the skin as possible with fine-point tweezers and pulling straight upward in a slow, steady motion to prevent the mouth parts from breaking off and remaining embedded in the skin. 

Successfully removing a tick is an important first step, but it does not eliminate the risk of infection; it only reduces it. Because tick-borne illnesses can take days or even weeks to develop, it’s important to closely monitor both the bite site and your pet’s overall health for several weeks following removal.

In some cases, preserving the tick can also be helpful. Veterinary guidance from the 

 notes that keeping the tick may assist with later identification if illness occurs:

“Save the removed tick, wrapped in cellophane tape or in a vial with alcohol, in case it is needed for identification later. The tape or vial can be sealed in a plastic bag, labeled with the date found, and frozen. If illness develops, identification of the tick and the day it was discovered may aid the physician in recognizing which infection was most likely transmitted and allow prompt, appropriate treatment.”

Storing the tick in this way can provide valuable context for your veterinarian or physician, helping them better assess potential disease risks and make more informed decisions if symptoms appear later.

Ticks may be small and hard to spot, but the health risks they carry are significant and often delayed. With the right knowledge and consistent habits, you can dramatically reduce your pet’s risk of serious illness. From daily tick checks and quick removal to close monitoring in the weeks that follow, every step you take plays a role in protecting your pet’s long-term health.

 remains the most effective strategy for all pets. Year-round tick control, combined with routine inspections and quick action when a tick is found, helps break the cycle of exposure before disease can take hold. Staying calm and informed ensures you will respond quickly and confidently when that time comes. 

 makes it easier to stay consistent with your pet’s prevention routine, so you’re always prepared when ticks are waiting to attach. By combining reliable protection with simple, proactive habits, you give your pet a stronger defense against tick-borne disease. Small, consistent actions today can go a long way in helping your dog or cat stay healthy, active and protected throughout the year.

Found a Tick? Here's What to Do Next

As spring arrives, environmental allergens begin to rise, triggering symptoms that are uncomfortable for many pets. When pollen and other allergens are released into the environment, dogs and cats can go from enjoying time outside to feeling uncomfortable every day. If your pet is scratching nonstop, rubbing their face or waking up with watery eyes, seasonal allergies are likely the cause. Recognizing the symptoms early and understanding what is happening in their body can make a meaningful difference in their comfort and overall quality of life.

An allergy is an exaggerated immune response to a typically harmless substance known as an allergen. These allergens are often proteins found in plants, insects, animals or certain foods. With repeated exposure over time, ranging from months to years, the immune system can become sensitized. Once this sensitization occurs, future exposure can trigger an overactive inflammatory response in the body, leading to the clinical signs seen in allergic pets (

A common misconception among pet owners is that allergens remain outdoors, but in reality, pollen and other microscopic particles easily enter the home through open windows and doors. Once indoors, these allergens can linger in the environment, meaning even indoor dogs and cats may experience ongoing exposure and symptoms during peak allergy seasons. Although dogs are diagnosed more frequently, both dogs and cats can be affected by seasonal allergies. Symptoms often develop gradually and may worsen over time with repeated exposure as the immune system becomes increasingly reactive, with mild seasonal itching potentially progressing into more persistent or severe discomfort in later years if not properly managed.

Allergy symptoms in pets often differ from those seen in humans. While people commonly develop sneezing and watery eyes, dogs and cats are more likely to show signs through their skin. The most common indicator of spring allergies is persistent itching. They may scratch under their legs, rub their faces against furniture or lick and chew obsessively at their paws. Ear inflammation and recurrent ear infections are also symptoms of seasonal allergies. Pets may shake their heads or scratch at their ears, and these symptoms should be taken seriously and evaluated by a veterinarian (

One of the more serious cases linked to spring allergens is canine atopic dermatitis, a chronic and intensely itchy skin disease triggered by environmental allergens. According to 

Cornell University's Riney Canine Health Center

, atopic dermatitis may affect as much as 10 to 15 percent of the dog population, with dogs typically beginning to show signs between six months and three years of age.

The good news is that spring pet allergies are very manageable with the right approach. Managing a pet with seasonal allergies requires a combination of therapies alongside frequent communication between the veterinary team and the pet's family. For pets with moderate to severe seasonal allergy symptoms, veterinarians have several proven prescription options. Veterinarians may recommend anti-itch medications such as 

, an oral chewable approved for dogs, or 

, an oral immunosuppressant medication available for both dogs and cats that can take around a month for effects to be seen and is intended for long-term allergy control. For cats, medication options are more limited. Some feline allergies can be managed with daily low doses of immunosuppressive drugs such as 

Keep in mind, these medications may cause side effects and should only be used under the guidance and supervision of a veterinarian, with appropriate monitoring throughout treatment. Working closely with your veterinary team, tracking your pet's symptoms across seasons, and staying consistent with treatment is what makes the biggest difference in long-term comfort and quality of life.

While prescription treatment is an important part of managing spring allergies, what pet owners do at home between veterinary visits matters just as much. 

recommends weekly to biweekly baths in dogs with a history of flares due to microbial overgrowth; routine use of 

 may help decrease the incidence of secondary infections. Catching secondary infections early prevents them from layering additional discomfort on top of already irritated skin, and keeping your veterinary team informed throughout the season is one of the most important things you can do for your pet's comfort and long-term health. 

For cats, management may include periodic bathing with gentle, soothing ingredients such as oatmeal, along with veterinarian-prescribed 

 to calm irritated skin. Because cats can be more sensitive to products and grooming, it is important to use formulations specifically recommended by your veterinarian based on your pet’s individual needs.

Additional preventive steps can make a meaningful difference. Keeping up with 

 and limiting outdoor exposure on high-pollen days are two additional steps that can reduce the burden on your pet's immune system during spring. The 

 recommend prescribing a flea and tick preventive and discussing compliance with the client as a core step in managing the allergic patient. Even pets with no history of flea allergy can experience a worsened itch response when flea exposure combines with an existing environmental allergy. 

Spring pet allergies are not a condition that can be fixed once and forgotten. The most important thing to understand is that seasonal allergies in pets are very manageable when addressed early and consistently. Recognizing the symptoms before they worsen, working closely with your veterinary team to find the right combination of treatments, and staying alert at home throughout the season all contribute to a meaningfully better outcome for your pet. No two animals respond to allergy season the same way, which is why the relationship between pet owner and veterinarian is so central to success.

There is no single solution that resolves seasonal allergies overnight. Managing them well is about building a plan over time, one that gets refined season after season based on how your pet responds. With the right guidance, the right treatment and a little extra attention at home, most pets can move through spring with far more comfort than their allergies might initially suggest is possible. If you think your pet may be experiencing seasonal allergy symptoms, reaching out to your veterinarian is the best first step toward giving them the relief they deserve.

Spring Pet Allergies: Symptoms & Survival Tips 

Dogs bring immense joy to millions of households, but being a responsible owner means recognizing that they are animals with instincts and boundaries. We may believe our pets would never bite someone, but the reality is that any dog can bite under the right circumstances. In the United States alone, “

more than 4.5 million people are bitten by dogs each year

”, with nearly 800,000 requiring medical attention (AVMA). Understanding that even gentle dogs can bite and learning how to prevent it is the first step in keeping both your family and your dog safe.

National Dog Bite Prevention Week, observed annually during the second full week of April, is dedicated to educating the public about responsible dog ownership and the strategies that reduce dog-related injuries. The reality is that dog bite prevention is actually within our control, starting with understanding why dogs bite and learning to recognize dog body language warning signs before a bite ever occurs.

Why Dogs Bite: Understanding the Triggers

A common misconception is that dog bites happen without warning. In reality, dogs typically bite in response to specific situations, often when they feel stressed, fearful, in pain or threatened. Beyond defense or fear, dogs may also bite due to territorial instincts, underlying illness or injury, neglectful care, or a lack of proper socialization. It’s also mentioned, “

even well-trained, gentle dogs, are capable of biting when provoked, especially when eating, sleeping or caring for puppies

If a dog is suffering from an undetected health issue such as arthritis, a dental infection, or an ear problem, they may snap or growl when touched, even if they have never shown aggression before. This is why regular veterinary checkups are an important part of bite prevention. Pain or illness can dramatically alter a dog’s tolerance for handling and interaction. 

A Dog’s Body Language: Warning Signs Before a Bite

Dogs rarely bite without first communicating discomfort. The problem is that many people don’t recognize or respect their signals. Dogs primarily communicate through body language. When feeling stressed or threatened, they may display subtle cues before a bite happens. According to canine behavior experts, dogs often show warning signals when they are uncomfortable or anxious in a situation (

Some of the most common warning signs include:

ᐧ Whale eye (when the whites of the eyes are visible)

ᐧ Yawning, lip licking or turning the head away

Unfortunately, these signals are often misunderstood or ignored, especially by children who may interpret them as playful behavior. When these warnings fail to stop the interaction, the dog may escalate to snapping or biting.

Prompt and proper care reduces the risk of infection and other complications. The 

 shares instructions on what to do next: Wash the wound gently and thoroughly

with soap and warm water for several minutes to remove bacteria or any debris. Apply gentle pressure with a clean cloth or sterile bandage to stop any bleeding. If the bleeding is severe or does not stop, seek emergency medical care immediately. Once the wound is washed and the bleeding has subsided, apply an antibiotic cream and cover the injury with a clean bandage.

Consider reporting the bite to local authorities, particularly if the dog’s vaccination status is unknown or if it poses a public safety risk. Prompt care and reporting ensure both your safety and the safety of the community.

While dog bites are a serious concern, they are largely preventable through proactive care and proper education. Pet parents can significantly lower the risk of injury by understanding canine motivations, recognizing subtle warning signs, supervising when around children and practicing responsible ownership. Taking preventative measures is most effective when they address the physical and behavioral needs of the pet through every life stage. 

A healthy dog is also a safer dog, as underlying pain or illness can often lead to irritability and unexpected reactions. Staying up to date with veterinary care is essential. Services like 

 simplify the process by providing vet-verified medications, personalized pre-sorted pouches and working directly with your vet to ensure prescription accuracy. By combining these logistical health tools with a deep understanding of canine behavior, owners can create a secure environment where both pets and people thrive together. 

Dog Bite Prevention Week: What Every Owner Needs to Know

Unlike a broken bone or an open wound, heartworms do not advertise their presence with a limp or a whine. Because heartworm symptoms in dogs and cats are often invisible, internal damage can occur before a pet parent even notices any red flags. This is why heartworm prevention is one of the most important topics your veterinarian will ever discuss with you. The first step in protecting your pet from heartworm infection is to understand the parasite that causes it and where it comes from. 

Heartworms can only be transmitted from animal to animal by mosquitoes

 explains. A mosquito bites an infected dog, picks up immature heartworms in the process, and then passes them along to the next dog it bites.

Once inside a dog, those larvae take about six to seven months to grow into adult worms and settle into the heart and pulmonary arteries,

 where they can live for “five to seven years

Cornell University College of Veterinary Medicine

). The worms grow surprisingly large, and over time, the physical burden they place on the heart and lungs can become serious.

One of the most difficult realities for pet owners is that the early stages of heartworm disease are often completely silent. It can take several years before dogs show any visible signs of infection, and by the time a persistent cough or unusual symptom appears, the disease has already quietly progressed. Waiting for your pet to seem sick is not a safe approach and can be a risk to their long-term health.

Heartworm disease is more widespread than most pet owners realize, and the numbers are increasing every year.

 While many believe the risk is limited to humid, southern climates, Heartworm disease has been detected in all 50 states

, and its reach continues to grow as climate shifts expand mosquito populations and the relocation of pets across state lines introduces the disease to new areas (

According to a recent American Heartworm Society (

) survey, data reported by the AVMA reveals that over 68% of dogs in the U.S. leave their veterinary clinic without a single dose of heartworm preventive. This gap in protection makes the "chance of infection" higher than ever. As the environmental and social factors evolve, the reach of this life-threatening disease continues to grow nationwide.

Because heartworms damage the heart and lungs slowly over time, symptoms may be subtle at first. Early warning signs in dogs may include:

As the infection progresses, symptoms can become more severe. Dogs may develop difficulty breathing or a swollen belly due to fluid buildup. In the more advanced cases, an abundance of worms blocks blood flow through the heart, creating a life-threatening emergency that often requires immediate surgery.

Cats can also develop heartworm disease, although it affects them differently. Because cats typically harbor fewer worms, the disease may present as sudden respiratory distress, coughing, vomiting or asthma-like symptoms. In some cases, sudden death may be the first and only sign of infection. According to the 

, even a single worm can cause serious illness in cats.

What Treatment Looks Like (Why Prevention Is So Much Better)

If a dog tests positive for heartworm, serious treatment challenges lie ahead. An ingredient called 

 is the only FDA-approved drug for heartworm treatment in dogs

, and it must be administered by a veterinarian through a series of injections (

). Following treatment, dogs require restricted exercise for up to six weeks because active dogs are at risk for potentially fatal blood clots in the lungs. The process is physically taxing on the animal and emotionally exhausting for the family watching it happen.

Monthly preventive medications, chewable tablets, or topical treatments are accessible and highly effective.

What Every Pet Parent Needs to Know About Heartworm

You know your pet better than anyone. You notice when the morning shuffle to the food bowl takes a little longer than usual, when the tail wag is missing from the afternoon greeting, or when jumping onto the couch happens less and less. These are the moments that signal a joint flare-up, and for the millions of pet owners managing a dog or cat with arthritis, they're a familiar and frustrating reality.
