As an alternative to rawhide---which has choking risks for dogs, I love these. Even though my dog is 80#, I purchase the small size. They become a nice snack treat. There is no mess left behind and I am not fearful of him choking on the last piece as I am with raw hides. They are easy on his teeth and may help to remove plaque as he chews them. My dog is diabetic and thus far, does not have a negative effect on his glucose or fat intake.
Our rescue dog was very aggressive to anyone entering our home, including biting them. We started using this and in two days it all stopped! Our friends couldn't believe this was the same dog. I don't know how it does it, but best product ever!
