My 6 month old Shih Tzu is 5.5 lbs and she LOVES to chew. She cannot get enough to chew. The vet said no rawhide for digestion reasons. I've tried the Nylabone and Nylabone edibles. The Nylabones she just gives up on. I don't know if they lack or run out of flavor but she ignores them. The Nylabone edibles she can break down and consume in minutes. I would like to give her a bone of some sort that will keep her interest. Can I give her Pig Ears to chew on? Are there other safe alternatives? I don't want anything that is going to mess with her digestion because that is sensitive enough. I just want something she can safely chew on that is tasty and I don't have to worry about her tearing into it. She has a Kong that we stuff with treats or one of those long bones designed for the Kong. She can break that down in minutes and is looking for more. I'm not interested in filling her belly just keeping her teeth occupied. Suggestions? Pig Ears? A visit to a butcher shop? If so what are safe bones for chewing? Thanks for your time.
