Works well but my dog doesn't like it

Have been giving this to my Labrador dog for 3 years now and she does not like it. I see the ads on TV all the time of how the dogs just love their medicines that are chewable but not my dog. I have to use a sharp knife and cut it into pieces, cover it in peanut butter and shove it down her throat. It's a struggle every month. But I guess it's worth it cuz it does seem to work. Wish there was something better tasting that this dog would like.

Have to cover in peanut butter

This chew works out fine for us. My golden retriever will eat anything...except this chew. I rolled it in all kinds of meats and even stick it on a bite of pizza and she would eat the food but spit the chew out every time. I used to find them around the house thinking she had eaten it but finally tried rolling it around in peanut butter. She pretty much just swallows it whole but at least I don’t have any trouble anymore.

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!

dogs don’t like it

It seems so be working because my dogs don’t have heartworm or parasites, but I’ve never had so much trouble getting them to take a pill. They are constantly spitting pieces out and it takes forever to keep refeeding and gets all of the pieces down.

Doggy approved!

We use this on our vizsla and he has never had parasites or heartworm! Our heartworm tests and stool samples are always negative at the vet. Dog thinks it's a dog treat, so the flavor must be tasty. Also, we have not experienced any side effects. Works for us!

Perfect for my lab

At last I've found a heartworm med that doesn't make my 11 yr. old chocolate lab sick. After much trial and error, her vet suggested Interceptor. It contains no ivermectin or pyrantel which were the culprits of intolerance for my dog. Also, it was easy for me to have Chewy handle the internet prescription. Overall, a win win for my dog (and me). Thanx.

He liked it!

My dog refuses to eat the brand that his vet carries (however, he has no problem eating deer and rabbit droppings, sticks, stones, trash, etc.), sooooo....the vet recommended Interceptor Plus through Chewy. It was a great idea! He actually liked it, so I can now rest easy that he is protected. I expected to wait a while to receive it since this is a prescriptioned medication, but it was here in about 2 days. Wonderful service! I love! Thank you!

Automatic Refill

Happy with customer service. The only thing is that I got a 12 month supply of Interceptor Plus and the automatic refill will come in 8 or 6 months. Why don't you have 12 automatic month refill when getting a 12 month supply?

Do not buy - dogs refuse them

I’ve never had either of my dogs refuse any pills, supplements or food and they will absolutely not eat these. It’s a full on assault war to get them down their throats bc they won’t chew them. I’d never buy them again This is not a reflection on chewy as they are always an amazing company to deal with Choose another HW prevention unless you want to go to war with your dogs :(

Interceptor Plus

All of my pups (2 Boxers and a Lab mix) are on this medication and have been since they were babies. No issues with the medication.
