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)

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.

Heart "Cookies"!
Oct 13, 2011

Our Chihuahua is resting more soundly knowing that his "heart cookies" are in the cupboard now. We have been using Heartgard for several years now and it's a party everytime the chihuahua hears the words "heart cookie." Then we get his dose and he enjoys it. We are happy that he is heartworm free and we can rest almost as soundly has he can!

Great Product at a Reasonable Price

My Pit Bull, Deuce, is getting old and the Heartgard Plus is the prefect product for him. Easy to give, works great, and a very healthy happy dog.

Heartgard from Oz-Best Export ever!
Oct 12, 2011

Living in the intensely mosquito-laden area of the East Coast of the U.S., the menace of heart worm infestation is a real concern. Thanks to Heartgard I rest easy knowing my dogs are fully protected. The dogs get a tasty treat, and I know I've kept them from harm. WIN-WIN! Buying from Pet Shed was a SNAP, saved me money, and delivery from Oz to this Yankee Gal was swift. Thanks Heartgard, and thanks Pet Shed!!! WIN-WIN-WIN!!!

My dog's are pretty picky when it comes to what they eat. They love Heartgard! I am so happy it is so easy to give to them once a month. They won't eat other meds that must be given by mouth, so I was nervous. But, we have never had a problem giving Heartgard. They have also had negative heartworm tests for many years while they have been taking Heartgard- never a positive test.

Best Place to Buy

Ordering from PetShed is fast and easy. Although it takes a little longer to get to the US than some other companies, it is definitely worth waiting a few extra days when you consider the monetary savings. Along with my vet, I am sure that many other vets don't like to see business go elsewhere and are reluctant to send perscription requests to companies. Instead of bothering my vet, I am able to just order immediately from PetShed. It is wonderful to receive the same medication my vet sells, but for a lot less!
