But before we proceed and discuss the benefits of the Heartgard plus heartworm preventive, let’s get acquainted with these parasites roundworms, hookworms, and heartworms.

Roundworms (Toxocara Canis, Toxascaris leonina, and Toxocara cati)

Roundworms are the round-shaped worms that live in the intestinal tract of your pet and feed on the nutrients that were supposed to benefit your pet. 3-6inch in length, these worms grow big in size and in their adult stage, female roundworms lay eggs that are excreted with the stool.  These eggs take several weeks to mature into larvae that eventually infect another host.

Almost 14.5 percent of dogs in the US are suffering from roundworms.

Your pet may become infected with these larvae when they feed on the stool consisting of larvae/eggs or eat other larvae hosts like rodents, birds, roaches, and birds. These parasites are even passed by the mother pet to their kids while birth or after birth while nursing.

Common symptoms that your pet will show are –

  • Pot-bellied appearance
  • Diarrhea
  • Vomiting
  • Weigh loss
  • Dull coat
  • Lethargy
  • Weakness

Hookworm infestation is more common in dogs with almost 19% of dogs in the US and Canada carrying these worms in their intestine. These worms are very small half an inch long worms with the hook-like cutting mouth parts they get attached to the intestinal walls of your pet and feed on the blood.

The eggs of hookworms are so small that they can be diagnosed only through the microscopic examination of the feces.

Your pet may get affected by these worms by ingesting eggs present in the feces. Moreover, these worms can even penetrate your pet’s skin. The symptoms that can be observed are – pale look and anemia when the infestation is severe. There is also a huge risk of life in case of heavy infestations.

Heartworms (Dirofilaria immitis)

As you’ve read earlier in this blog, these worms are the nastiest worms existing in the world. Males are as long as 4-5 inches while the females are 10-12 inches long. These worms are transferred from one infected dog/cat to another healthy dog/cat by mosquitoes. When the mosquito bites an infected host it sucks in the heartworm offspring called microfilariae which becomes infectious while they live in mosquito and is injected into a healthy dog/cat’s body in the subsequent bites.

The worst thing about these infestations is that the symptoms become noticeable only after 5-6 months of infestation when the larvae have already matured into an adult. The clinical diagnosis is also possible only after 5-6 months of infestation. However, these nasty creatures can survive 7 years in a host’s body.

Symptoms that can be rarely observed in the initial period are – coughing, feeling tired, breathing issues and in severe cases, heart failure.

There are several treatments available for hookworms and roundworms but for heartworms, the treatments are limited and have critical side-effects hence it would be wise if you opt for a preventive that stops these infestations.

Now Getting Back To Heartgard Plus

Heartgard Plus

One of the most trusted and followed heartworm preventives in the US is Heartgard Plus. Let’s have a look at the working process and the benefits of an apt heartworm preventive called Heartgard plus.

How Heartgard Plus Works

The tasty beef-flavored chew contains ivermectin that kills the newly transmitted infectious heartworm larvae (microfilaria) in your pet’s blood vessels thus eliminating the threat of heartworm infestation. However, if there are adult heartworms present in your pet’s body then ivermectin will not be able to kill them and you will have to take the help of your vet. On the other side, Pyrantel is very effective on both the fronts i.e. treating the worms and preventing the worms because pyrantel paralyzes the existing worms like roundworms and hookworms, as a result, it helps the body to excrete them with the stool in a natural way. If given regularly Pyrantel can kill ingested eggs as well thus breaking the worm cycle.
