INTERCEPTOR PLUS may be offered to the dog by hand or added to a small amount of dog food. The chewables should be administered in a manner that encourages the dog to chew, rather than to swallow without chewing. Chewables may be broken into pieces and fed to dogs that normally swallow treats whole. Care should be taken that the dog consumes the complete dose, and treated animals should be observed for a few minutes after administration to ensure that no part of the dose is lost or rejected. If it is suspected that any of the dose has been lost, redosing is recommended.

You can give Interceptor Plus to your dog by hand or add it to a small amount of dog food.

  • Great Product, Poor Packaging

    By on

    5 stars on product - 2 stars on packaging - We recently moved and I didn’t want to switch vets just to get a refill on my dog’s Interceptor and Bravecto. I was so excited to use Chewy and they contacted my vet for me! Shipping was quick; however, the medicine came in an envelope and everything was crushed! I’ve never had an issue with Chewy before, so it was a little disappointing. As for Interceptor, my year old rescue has been on it for 7 months and hasn’t had any issues. He’s indoor/outdoor, exposed to other dogs, and was sickly when we got him with several allergies. Now he’s doing great and has never had an issue with Interceptor. It does it’s job at an affordable price!
