My girls love them and Tatiana is 6 almost 7 months. She has been chewing on them since I brought her home. I just limit the time they chew on them. Some dogs they might get diarrhea. My girls have not had this issue with bully sticks/pizzles. I too, make sure it is a product of the USA. As with all chew items, there is a danger of choking, breaking a tooth, etc......just give it when you are in attendance!
