How Does Heartgard Plus Works for Dogs?
Heartgard Plus contains two active ingredients that work together to provide comprehensive parasite protection for your dog.
- Ivermectin is responsible for preventing heartworm disease by inactivating heartworm larvae before they can develop into dangerous adult worms. By stopping heartworms at the larval stage, Heartgard Plus ensures that infections do not progress to life-threatening levels.
- Pyrantel Pamoate is an added defense against intestinal parasites, specifically hookworms and roundworms. These parasites can be ingested through contaminated soil, feces, or even a mother’s milk. Pyrantel works by paralyzing these worms, allowing your dog to expel them naturally.
💡 Did you know? Heartworms are transmitted through mosquito bites, and even dogs who stay indoors are at risk! Consistent monthly prevention is the only way to keep your pet protected.
