It’s a WINNER!
Was previously giving my Pom Interceptor Plus for heart worm but she obviously didn’t like the taste because no matter how I tried to disguise it, I always found it left on the floor. The bacon flavor in Iverhart Max was an instant success since my pet rapidly chewed it with a smile on her face.

My vet recommended this product to us for my 7 lb chinese crested Poppy. To my surprise she really enjoys the taste and will eat it within seconds.
