My German Shepherd used to devour these things like nothing. For years, we struggled with her and the rest of the crew to brush their teeth, finally coming to a mixture of peanut butter and baking soda to get them to let the toothbrush in their mouths. These little godsends made our work much easier, at least with the shepherd, who liked the taste so much she started bugging out every time we popped the toothpaste. The smell is pleasant, unlike many of the other dental chews we had tried, and long lasting, unlike the dental mints we'd been relying on prior for an in between breath killer. All of our dogs loved the taste, just my baby girl was besides herself over them. Side Effects Almost clean enough that I was able to increase the time between brushings. Lovely breath smell, which is always my first rating on dental products, lasted longer than expected, and the bad smell stayed away for a few days.
