Its efficacy makes it a popular choice for managing parasitic infections in animals, including dogs.

Ivermectin is available in several formulations, including tablets, oral liquids, and injectables. The specific form and dosing depend on the condition being treated, the dog\’s size, and the veterinarian\’s recommendations.
