Excellent product

When my Greyhound came to us from the track, hookworms were in tow. Unfortunately it happens, but once we got that under control this was suggested by our vet. It has worked very well as in hookworms never returned and I know preventing it is a must.

Buyer beware - make sure you are in communication with your vet BEFORE you order. Our dog has been around 48 pounds, and tipped over 50 when this order was placed so the vet changed the order to be for the 50-100 pound dosage, but then dipped back under 50 pounds by the time it arrived. Chewy does not allow returns for any reason, even though the packages were never opened and are sealed. Never ordering from here again, as I'm now out $160 for this and the Credelio tablets I ordered as part of this order.

Quality product

I I have used interceptor for the last 8 years for my 12-year-old dog Layla. She has had no problem with heartworm and the other ingredients also help with other parasites. She did have one of the parasites that the medicine is supposed to prevent one time. And the company reimbursed me for the blood test and the medicine she had to take to get rid of the parasite.

To their health

Works well for my dog. I started my dog on this to prevent heartworm. The advantage is it also prevents all the other baddies too.

Great product at a great price!

Been using this for my pup for years. Chewy was instrumental in cutting through the "red tape" from my veterinary clinic. They are great at knowing exactly how to deal with your vet & make the prescription process simple. I trust Chewy for this & the major cost reduction & many other reasons. Thanks Chewy Team!
