Heartgard Plus

Heartgard is a monthly medication for the prevention of heartworms in dogs. Heartgard tablets prevent heartworm disease in dogs by eliminating the heartworm larvae that infect the dog in the month before treatment.

Heartgard has a wide safety margin in all breeds of dogs, including pregnant females, breeding bitches, stud dogs and puppies six weeks of age and older. Dogs over six months of age should be tested for heartworm disease prior to using Heartgard, and tested annually thereafter.

  • Prevents heartworms (a potentially deadly disease)
  • Easy monthly dose (each pack contains six doses)
  • Each chewable tablet contains Ivermectin

You pay $25.95

Product Detail: Heartgard Plus

Heartgard Plus eliminates the tissue stages of heartworm larvae (Dirofilaria immitis) and removes adult roundworms (Toxocara canis, Toxascaris leonina) and hookworms (Ancylostoma caninum, A. braziliense, Uncinaria stenocephala) from dogs. Heartgard will control heartworm infections acquired in the previous 4 months provided that monthly treatment is continued for at least 12 consecutive months.

The chewable beef cube is highly palatable and most dogs will accept Heartgard Plus as a treat.

Dosage and Administration: Give one chew each month, preferably on the same day or date. The cube may be offered by hand or added to the food. Dogs should be closely observed for several minutes following administration to make sure that the entire dose has been consumed.

I have purchased Heartgard Plus for 3 years now. Petshed is the best place to purchase. They have a great quality product. The dogs love the Heartgard plus, and have been heart worm free. !!

Happy to have been told about Pet Shed!

Although I hate the idea of giving my animals products such as this, but the thought of the alternative is worse! Taking care of your animals as they should be has gotten so very expensive here in the US and continues to climb. I have 2 large and 2 medium rescue dogs, as well as 8 rescue cats. I would be rescuing more with all the room we have on our ranch, but I can't afford it any more and that is very sad because its the animals that suffer! I found your site though someone and you have saved me quite a bit of money on the Heartguard! My vet's prices have gotten out of control, especially for the large dogs. I also noticed prices on your other items & it seems all is reasonable!! Thank you so so very much!!

This product is great. My dog eagerly takes it and I have no problem with its availability. Certainly would recommend as an easy heartworm preventive medication!

Heartguard Plus takes care of my dogs preventative needs regarding heart and hook worms. I live in a area with lots of heartworm positive dogs and lots of mosquitos and it is a comfort knowing my dog Dingo is protected. She loves the meat flavored snack style "nuggets" right out of the pack. She sits and puts out her paw to beg for the "treat" which is actually her medicine. Good stuff.
