dog food order

Just a quick note. I have a 30 lb beagle and have been getting royal canin since we had the dog, I asked rep to switch to sr dog, food. Iwas sent food for a large dog. Just a suggestion, be specific on what you want. This is not a big deal. .

Interceptor PLUS does not work at all.

I've been using this product for over two months. My dog is loaded with ticks, new ticks every day. Now I've wasted over $50.

Twice the Price from VET

Glad Chewy offers this product. If I bought it from my veterinarian, it was twice the price.

Interceptor Plus

Very happy with my order of Interceptor Plus from Chewy. Much less expensive than when I would order from my vet's office. Also, received by mail very quickly. I will continue to order my pet meds from Chewy.
