Rated 5 out of 5 Interceptor We have used this since my Aussie has been a puppy with no complcations at all. January 28, 2012
Rated 5 out of 5 Ozzy's Grandma Our daughter has a very spoiled and loved Jack Russell Terrier and he just loves these. He gets his once a month treat and we have no problem getting him to take this. June 20, 2011
Rated 5 out of 5 Support your local vets! I support my vet and will by my precriptions there. If this online pharmacy trend continues, you're all going to put your vets out of business! Then who's going to write the Rx?!? May 7, 2011
Rated 5 out of 5 Interceptors I have been using interceptors for years now. They work so much better then heart guard, is what my vet told me. I usually buy pill pockets to put the pills in to give to my dogs. May 6, 2011
Rated 3 out of 5 No great deal My vet charged me the same price so no big price savings for me! April 22, 2011
Rated 5 out of 5 Dogs are special friends! Vet started giving this product to my dog two and half years ago, she suggested crushing it and putting in dab of peanut butter - works great and he is a very healthy dog. April 21, 2011
Rated 5 out of 5 Per my Vet We were giving our 1 year old Boxer/Border Collie mix Heartguard plus until her most recent yearly check up. The Vet stated that in order for Heartguard to fully work it had to be fully chewed, which MOST dogs do not do...With Interceptor, just swallowing it works as it dissolves into their bloodstream...My dog takes the pill with no other food necessary..No worms and a healthy puppy still!! Will buy on Petcarerx instead of vet as it is MUCH cheaper!! April 17, 2011
Rated 5 out of 5 How to get your dog to swallow Interceptor First I give my Silky a small piece of cheese. I place the tiny pill mushed up into a 2nd piece of cheese (cheeseball). He gobbles it up. November 12, 2010
