My dogs love rawhide. The worst, junkiest, made-in-China stuff if the can get their paws on it. I've looked long and hard for a substitute. I like them to chew because it's a natural activity and good for their teeth. They don't like the natural alternatives like hooves, bully sticks, or even the plain American-made rawhide products. I finally found something that I'm thrilled about, called Smart Bones, an alternative to rawhide. It's digestible, made of a vegetable outer coating and real chicken in a food grade facility with oversight. They're priced comparably with natural treats like bully sticks but less messy and dogs LOVE them. I found them cheapest on Amazon. Go through Sheltie Nation and the site gets credit. Just search Smart Bones. They come in chicken, peanut butter and dental varieties. Four paws up!
