    We have been using Interceptor tabs for about 9 years and it has kept our pup healthy with no side affects. We moved to Texas and our new vet does not carry it in house so we discovered Chewys and they worked with our vet. Verified the RX and sent us what we needed. It was easy and pain free. Thank you Chewys!

    I have used this product for years for my 2 small breed dogs. It is easy to make them swallow the tablet. I had used the other brand but my dogs don’t consider the other brand a dog treat.

    Was happy to see Chewy carry medications. We order our dog food from them and needed to place an order for Interceptor for our new dog. I did a search on their website and to my surprise, Interceptor showed up! They contacted our vet for the prescription and it was filled and mailed out promptly. Have used Interceptor for years on all my dogs without any problems.
