If your dog pet has an infection with heartworms or is at a high risk of developing one, it could be an incredibly frightening experience. Make sure that your dog is taking the heartworm preventative medication.

First, What is Heartworm Disease?

Heartworm disease is caused by parasitic worms known as Dirofilaria immitis. The worms reside in the heart of an animal’s lungs, and arteries.

The disease itself isn’t transmissible and is not able to spread from animal to animal. The worms only reproduce following exposure to a mosquito infected that is the sole transmitter of the disease.

If a mosquito feasts on an infected animal, and then bites another animal and transmits the infection, this is where the transmission happens.

The symptoms of heartworms are coughing, exercise in sensitivity, bleeding, and an unhealthy body condition. It is of course that prevention is best in fighting heartworm.

How Does Heartgard Work for your pet?


Heartgard is a prevention measure for heartworms: it kills the larvae that are infected before they get the chance to grow into adult heartworms, which can cause diseases and other harm.

Heartgard includes ivermectin, which is pharmaceutical medicine that is able to eliminate parasites.

It causes neurological damage to parasites, which then kills the parasites. Ivermectin does not just kill parasites that are found inside. It is also able to eliminate external ones too such as mites, lice, and Demodex. Therefore, Heartgard does double duty in the case of parasites.

How Do  Pet Dogs  Take Heartgard?


It’s not necessary to fool your pet (well we’d rather that’s not the case!). You must give your pet a small portion (one chewable tablet) every month. Additionally, the chews contain real beef, which is why the majority of dogs love the medication!
