Happy With Purchase

I've used Interceptor Plus for years now and it's the best of all the heartworm prevention products I've tried because of its multiple protection factor. I order from Chewy because it saves money and time and is always convenient.

Interceptor Plus is a very effective product & easy to give.

Interceptor Plus is easy to give & the dogs really love the taste (can't figure that out from the way it smells-chemical aroma). We have used this product for over 5 years and each time we do a sample test for parasites...the results are NEGATIVE. Each time, the results show no parasites!

Just what the Dr ordered

My vet recommended this brand for Zuki and I learned later that Interceptor is one of the few Heartworm preventatives that is safe for Heelers. So yay to my vet for prescribing the right stuff. Zuki looks forward to getting her "treat" for nothing.

Excellent product

Our rescue dog was heartworm positive. We made a commitment to keep her safe and healthy forever. This product does that! We are greatful.

Good product

I have been using this for years. I prefer it to Heartgard. It's less expensive, and since some of the herding breeds can be sensitive to Ivermectin, it's safer for them.

Took a bit longer than expected

I am always pleased with Chewy and the efficiency with orders, but my first RX experience took a bit longer than I expected.

Great Service

I love that I can get my heartworm meds from Chewy in such a prompt easy way. My dog has been on Sentinel heartworm preventative for years and this brand seems to be easier on his tummy.

No issues for me...

I had no problems with the pharmacy or verification of the RX for this or Nexgard, or any issues like some people reported.. matter of fact, I got my dogs meds quicker than my non pharmacy order! Meds seem to be working fine for my doggo! No side effects or anything negative.
