Amazing as always!

Amazing products with even greater service! They are always quick to respond to your questions and they call the vet the next day for your prescriptions. It’s very hassle free! I can always count on chewy!

dog throws up

I have given this heartworm preventative for 2 months now and both times he has thrown up. I am switching today. What a waste of my money!

PROTECT YOUR PUP AND SWITCH PREVENTATIVES!!

I have had my dog on Sentinel Spectrum for about a couple of years now, and he just tested positive for heartworms. He is an indoor dog who enjoys his walks and squirrel chases, but now that we are beginning treatment, he will not be allowed to do any of that for at least 4 months. Per the American Heartworm Association, there is only one heartworm preventative that is cleared for use during treatment, so we will be switching to that and keeping him on it even after treatment is complete. Save yourself and your pup the heartache, and SWITCH PREVENTATIVES!! It is not worth putting your pup through all of the testing, medication, and lifestyle changes.

Sentinel spectrum

I am upset that that I called about two charges on my account an was told that one pending removal. It was never removed and now it is to late to remove it. This product is great because it covers protection of so many things.

Great product!

My vet recommended this product since I am moving to Texas. She said my dog will be protected against parasites from mosquitoes. So I listened to her and my dog is doing well.

Just like a treat!

Remus thinks these are a treat! I usually break them in half so that he can chew them easier. I've been using this brand for over a year and am happy with them!
