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

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.

PetShed offers hands down the best prices out there for necessary heart worm and flea prevention meds. I searched other discount websites, amazon, and many more, and PetShed was the one with the lowest prices including shipping. Order arrived in timely manner. Will definitely order future medications and pet supplies from them in the future!

We have been using Heartguard Plus for our dogs for a few years. The introduction of Petshed allows us to purchase this important medication at a good price. one of our dogs tested positive for heartworms a year after we adopted her. Heartguard Plus gave us an option of ridding the worms without surgery. She is heartworm free and we would not use any other product. Thank you for allowing us to get this medication...

I've used this product for my dog. Petshed has absolutely the best prices and they ship promptly. Their products are always in date with a substantial expiration time so that there's no fear of having to use an expired product.
