How To Give Your Dog Interceptor Plus
Interceptor Plus (milbemycin oxime/praziquantel) is a chewable tablet flavored with real chicken that you give to your dog once a month, every month. Its overall acceptability is 96.6%, which makes dosing easy.
You can give Interceptor Plus to your dog by hand or add it to a small amount of dog food. Administer the chewables in a manner that encourages your dog to chew, rather than to swallow without chewing. If your dog normally swallows treats whole, you may break the chewables into pieces and feed them to your dog.
Make sure that your dog consumes the complete dose, and observe your pet for a few minutes after administration to ensure that no part of the dose is lost or rejected. If you suspect that any of the dose has been lost, redosing is recommended.

Vet Recommended, Pup Approved
By Connor on Jan 5, 2021
We live in an area where heartworm disease is especially prevalent. My local vet's office STRONGLY stresses the importance of keeping a dog on heartworm prevention anywhere, but especially here. They recommend this product strongly. I've had my pup on this for a year, and her heartworm tests come back negative. I'll take that as a good sign! No intestinal worms either. She doesn't care for this as much as other goodies (she's spoiled), but she WILL eat it. Another win! Usually medicinal things are spat out, so it's nice to not have to disguise the medicine with a bunch of other gunk.

Convenient Preventative Medication Option
By lakelp on Jan 21, 2021
Easy, monthly preventative soft chew to keep my puppy healthy. She ate it up like it was any other treat and now I'm all set until the same day next month. This brand was recommended by my vet but at a much higher price point at the vet's office. The added benefit of the savings from auto-ship on Chewy makes this product a triple win for me.

Best for older dogs
By Nora on Feb 15, 2021
Our dog is 10 years old and of course, set in her ways. This is the only med she will take! Our vet does not carry it. Chewy was right on it! Got it to the vet for approval and then to us very quickly. Extremely please!!

only one dog will eat these
By Finnyboy on Jan 17, 2021
I have two Boston’s. Only one will eat these. The other refuses, even if mashed into yogurt, peanut butter or cheese. He’ll lick the good stuff and spits these chews out however small the pieces. Have to find something else for him.

Hard as a rock
By Ashley on Feb 1, 2021
These are supposed to be soft chews. My dog who eats everything, will not touch these. She attempts to eat it, but its rock solid. It can't prevent anything if my dog won't/can't eat it.

Super easy to get prescriptions from Chewy
By Hooray1 on Jan 14, 2021
I've used interceptor from my vet before, but I saved money with Chewy! They even got the prescription from my vet themselves without me having to be the middle man, it was awesome!
