The risk is real

Prevent life-threatening heartworm disease 

Just ONE bite from an infected mosquito can transmit potentially deadly heartworm disease. Don’t take a chance with your dog’s health. Protect your dog year-round with HEARTGARD® Plus (ivermectin/pyrantel), the brand veterinarians recommend most.
