We switched our dog to this product after discovering one of our foster dogs had whipworms. I like that Sentinel protects against heartworms, fleas, and other intestinal parasites and it only requires one dose per month. I like using this better than topical flea control products because when the topicals rubbed off the dog onto our couch, it took the color out of the upholstery. Some topical products can also be toxic to cats. My dog has no problem taking Sentinel. We just give it to him after feeding him his morning meal and he thinks he's getting a treat.

After Interceptor withdrawn from the market, searched for the best replacement, and found Sentinel. My dogs (4) look forward to taking them as a "special treat." They will eat the pills with or without being in a pill-pocket. None of my dogs has had any potential side-effects and, of course, no worms or flea problems. The price is right, the integrity of this website is vet recommended, and I highly recommend this product.
