Heartgard Plus - Heartworm Chewables For Dogs Online

What is Heartgard Plus?

Heartgard Plus is a monthly beef-flavored chewable used for preventing heartworm in dogs. It also helps control roundworms and hookworms. Heartgard Plus is the #1 choice of vets and pets. It is the top heartworm disease preventative treatment as it eliminates all stages of heartworm. Its tasty flavor makes the dosing easy and its effectiveness is preferred by all pet parents. This monthly treatment has anti-parasitic and anthelmintic properties that work against mixed parasitic infections. Heartgard doesn’t just prevent heartworm disease for dogs 6 weeks of age and older; it also prevents roundworm and hookworm infections.

How does Heartgard Plus work?

Heartgard Plus contains two active compounds, Ivermectin and Pyrantel. These compounds combined act as strong anti-parasitic. They assist in killing worm larvae by causing muscle paralysis in worms, thus preventing the spread of heartworm disease. These active chemicals control the way nerve impulses flow through the neurological system of the worm, which results in the paralysis of worms and then death.

It should be noted that Heartgard Plus is only effective as a preventative for heartworm infection. You must first diagnose your dog for heartworm infection before administering any heartworm prevention product. If your dog has already been infected with heartworm, you should consult your veterinarian.

Nuheart - Generic Heartgard

Nuheart is a generic version of heartgard. It is an effective heartworm preventive with the same ingredient as heartgard. Nuheart has Ivermectin that destroys immature form of heartworms and controls heartworm disease in dogs. It is a highly palatable tablet which is easily soluble in water and can be mixed with food to administer it to dogs. The meat flavored tablet is to be given on monthly basis to prevent heartworm infection. The easy to dose tablet is suitable for dogs and puppies from 6 weeks of age.
