Heartworm Disease is an Invisible Threat

A Year-Round Risk for All Dogs

1 million dogs are estimated to be heartworm positive in the USA with cases reported in all 50 states.* The American Heartworm Society (AHS) recommends protecting dogs year-round and testing for heartworm disease every 12 months.*

1.  A mosquito ingests heartworm microfilariae after feeding on an infected animal.

2. Microfilariae become larvae and the mosquito can infect the next dog.

3. Larvae left on the skin develop in dogs.

4. Heartworm larvae migrate from the skin into the bloodstream of their new host, maturing as they go

5. Juvenile and adult heartworms primarily live in the pulmonary blood vessels of an infected dog.

6. Within 6 months of infection, adult heartworms are present in the pulmonary arteries.

7. When a mosquito bites an infected dog, the cycle can begin again.

Heartworms are gone!

When I first adopted my dog, she tested positive for heartworms and the vet suggested using Heartgard. After a full year of consistently taking Heartgard, she tested negative for heartworms!! The vet and I were quite sure that the test would still be positive (we expected her to have heartworms for a few more years) but this was a pleasant surprise.

Wish Chewy sold them in smaller packages

I have a puppy that will probably outgrow these before we use them up. I wish they were sold in three month supplies, or something else. He ate it immediately though with no bad reaction.

Easy to chew

My Vet only carries the hard chewable heart worm tablets. One of my rescued dogs has difficulty chewing them because of his underbite. These chews solve the problem AND he thinks it's a treat, so I have him sit and hand me his paw so he feels he's earned his reward.

Have Used for Years

This is the brand I have used with all my other dogs. Never a problem administering with taste and of course my companion pets have always been successfully protected. A side benefit is the reasonable price.

I have used this safely for years!

Especially if your small pup has a sensitive tummy, Heartgard seems to be better tolerated than some of its competitors. I gave it to my miniature Schnauzers (who lived to be 13-1/2 and 14-1/2) from the time they were old enough to take it, and am giving it to their now 3-month old successor as I write. Chewy was responsive, reliable, and worked well with my veterinarian to get this to me as soon as possible.

The product I ordered arrived in a very timely manner. I have been using this product on my dogs for many years and they have never had any problems with parasites.

The Chewy Pharmacy

This is my first experience with Chewy's pharmacy after working with a competitor for years. Chewy's pricing is largely the same, although for certain items it is more expensive. Promo codes (as available) help with the pricing (that, under the current economic conditions, is a critical issue). They seem to get in touch with my vet in a timely fashion so that the delivery is not delayed unnecessarily.

Customer service

I have sent a few emails on this item. Did hear back a few times but not the final time I sent a message. The item was sent earlier than expected which is great! But I was not home and sat outside for 3 days in 100 plus degree weather. I sent a picture of the inside information on temp. I would hate to give to my dogs without something in writing and it’s not good to give them.

do not trust Chewy

product fine, distributor ( Chewy ) very bad. this is not a comment on the product but on Unfair practices of Chewy. They did not pay attention to my cancellation of auto ship and then will not accept a return.
