I have given both my dogs dried "stuff" from Best Bully Sticks. I usually get a grab bag, and have never had any problems. I have gotten ears from pet stores, and they tend to be very greasy and get eaten like potato chips lol. The few ears I have gotten in the grab bag tend to be tougher and have lasted my 4 month old over a week! Tracheas tend to get eaten quickly and don't last. I guess if your pup doesn't get an upset stomach, you should be fine.
