Heartgard Plus For Dogs

As a dog owner, keeping your furry friend healthy and happy is a top priority. Protecting your dog's well-being is crucial to protect them from heartworm disease. Heartgard Plus is a medication that can help prevent heartworm infection in dogs. This blog will discuss what Heartgard Plus is, its potential side effects, and other important information.

What Is Heartgard Plus?

Heartgard Plus is a monthly medication for dogs that is used to prevent heartworm disease. The medication comes in a chewable tablet form and contains two active ingredients: ivermectin and pyrantelIvermectin is an anthelmintic that works by killing heartworm larvae before they have a chance to mature into adults. Pyrantel is a deworming agent that helps to remove and prevent the reinfestation of other intestinal parasites such as hookworms and roundworms.

Heartgard Plus is available in various strengths based on your dog's weight, and it's essential to give the correct dosage according to your dog's weight. Giving an incorrect dose can result in ineffective treatment or overdose.

How Does Heartgard Plus Work?

Heartworm disease is transmitted through the bite of infected mosquitoes. When a mosquito carrying heartworm larvae bites a dog, the larvae can migrate into the bloodstream and eventually mature into adult worms that can cause severe damage to the heart, lungs, and blood vessels.

Heartgard Plus works by killing heartworm larvae before they can mature into adults. The active ingredient ivermectin binds to the heartworm larvae's nervous system receptors, leading to paralysis and, ultimately, their death. Pyrantel works by paralyzing and killing hookworms and roundworms in the dog's intestinal tract.

It's essential to give Heartgard Plus every 30 days as directed by your veterinarian to ensure your dog is protected from heartworm disease.
