First, my old dog will actually eat these without disguising them in a slab of steak; that alone deserves a 5 star rating! We live on the edge of a greenway/open space, and the critters that visit us are typically parasite laden petri dishes. Despite Myla’s expertise at keeping the rabbit, raccoon, rat and other vermin populations in check, she has never needed a worming since being on Interceptor Plus.

The price has drastically increased

This used to cost us $60 for a 6 month supply back in 2022.. chewy is wonderful and this medication is fine but this has us questioning alternatives.

Love how easy it is to get renewed and shipped, don’t love how the delivery service drops the box in front of our garage.We could easy drive over it before realizing it’s there. Why can’t they drop the packages at the front door where we would look for them???

That's what it's supposed to do

How do you really know if it's doing what it's supposed to do? You wouldn't know unless it doesn't do it and then you end up with heartworms. For years I have used

How do you really know if it's doing what it's supposed to do? You wouldn't know unless it doesn't do it and then you end up with heartworms. For years I have used this medication on my Shelties and Collie always with clean blood work, no parasites.

Wonderful Customer Service

My prescription was delayed in delivery. As soon as Chewy received it, they shipped it overnight. I can't recommend Chewy enough.

It's the same as what I had gotten previously from my vet's office (compared the boxes), but I saved over $100. As for the taste of the chewable, my dog happily takes it. Shipping was amazingly fast.
