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)

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.

Great Value

I've been buying this product from PetShed for several years and my dogs have been totally protected from all worms, even though they are outside dogs and we live in the forest. The price has consistently been the best online.

My Dogs LOVE IT!

I have two Basset Hounds and this was the first time I used Heartgard. (previously used another brand). THEY LOVED IT! You would have thought I'd given them a piece of STEAK. Tucker even went into the trash after the little container thing it comes in and pulled it out and proceeded to lick it clean. Very easy and convenient for the dogs and the humans! I highly Recommend this product.

Great Product my dog loves.

I have used Pet Shed for years and ordered HeartGard for my beagle. He loves these and thinks they are treats. He comes running when I open up the package. Easy to use, No mess, and he eats the squares right up. He thinks he gets a treat and I know he is protected as well. No side effects of any kind and I am very happy with this product. I am ,also, Happy With Pet Shed. Fast Shipping and Good Costumer service. I highly recommend these for your dog and I so happy with Pet Shed and always will be. Thank you.

I always bargain hunt for my pets' medications (as well as my own) and Pet Shed is the ONLY way to go! It is the same Heartgard Plus you find in the States just for much cheaper and inexpensive shipping. Also it doesn't require a prescription so there is no hassle. I will only buy Heartgard Plus through Pet Shed for the rest of my pets' lives.
