Heartgard to Protect Pets from Blood-borne Parasites

USA Script Helpers

Heartworms are invisible threats that invade your dog’s pulmonary arteries and adjacent blood vessels. Without treatment, this disease is fatal to your beloved pet. Caused by a parasite known as Dirofilaria immitis, heartworm disease can lead to lung and heart failure. It is most common in the Gulf and Atlantic coast, but it has been diagnosed in all 50 states in the U.S. The good news is that heartworm is preventable. To combat this serious illness, Heartgard is prescribed.

What Is Heartgard (For Dogs)?

Heartgard protects your pets from blood-borne parasites and treats five species of intestinal worms. It is a flavored chewable administered during monthly intervals, with doses depending on your dog’s weight. Aside from preventing dirofilariasis or heartworm disease, it treats three species of hookworms:

  • Ancylostoma caninum

  • Uncinaria stenocephala

  • Ancylostoma braziliense

It also treats two species of roundworms:

  • Toxocara canis

  • Toxascaris leonine

How Heartgard (For Dogs) Works

Heartgard has been proven to protect against heartworm disease. It works by eliminating the tissue stage of heartworm larvae during the course of 30 days. As a result, the development of these parasites into adults is prevented. This medication is recommended by most vets and more than 2 billion doses have been prescribed. Dogs also prefer it for its beef flavor, so you would have an easier time administering it. This medication must be administered in a manner that encourages the dog to chew, rather than swallow whole. It may be broken down into tiny pieces and given during mealtime.

A Safe Brand You Can Trust

Affordable Heartgard has been clinically tested for the safety of your pets. In these clinical trials, the goal was to ensure the safety of your dogs during Heartgard treatment. Heartgard has shown a big margin of safety when given at the prescribed dose. Vomiting and diarrhea were rarely observed, the medication demonstrated no signs of toxicity. It is also safe for pregnant dogs and puppies aged 6 weeks or more.
