Recommended Dosage
Care should be taken that the dog consumes the complete dose, and treated animals should be observed for a few minutes after administration to ensure that part of the dose is not lost or rejected. If it is suspected that any of the dose has been lost, redosing is recommended.
Heartgard Plus should be given at monthly intervals during the period of the year when mosquitoes, potentially carrying infective heartworm larvae, are active. The initial dose must be given within a month (30 days) after the dog’s first exposure to mosquitoes. The final dose must be given within a month (30 days) after the dog’s last exposure to mosquitoes
For best results, give once a month on or around the same day without missing a dose . If treatment is delayed, whether by a few days or many, immediate treatment with Heartgard Plus and resumption of the recommended dosing regimen will minimize the opportunity for the development of adult heartworms.
Speak with your veterinarian and follow your pet's prescription for specific dosing instructions for your pet. Can be given by hand or with a small amount of food. Break into pieces to encourage chewing rather than swallowing whole. Store between 68° to 77°F (20° to 25°C). Excursions between 59° to 86°F (15° to 30°C) are permitted. Protect product from light. Remove only one chewable at a time and return the card with the remaining chewables to its box.
