These treats truly keep your dog "busy"! I wanted to find a good rawhide alternative that I could give to my pets a few times a week. Almost everything we tried, they would go through in less than ten minutes. I was really surprised that a Purina "Chewnola" bone would last as long as it does. It looks and smells like a human granola bar. My littlest one, Jasmine, (dachshund boxer) and Bandit (pit mix) can take up to 30 minutes to finish one chewnola. My American Bulldog, however, still gulps it down in 5-10, but he is a heavy chewer. They really like the taste of it and I like that if I am having guests over, I can give my pups this to keep them occupied. It also helps clean their teeth and freshen their breath. What I don't like is that the ingredients aren't that beneficial. They're basically just fillers. Since it's just a snack, I don't mind it every once in a while, but it would be nice to provide them a healthier alternative if possible. I definitely recommend it for your average dog, with no allergies. It does contain grains so be sure to avoid this if your pet is on a grain-free diet!
