My little dachshund Isabella has horrible breath. The vet said her teeth are fine. Mini Dachshunds tend to have this problem! It could be coming from her stomach. After trying just about every product out there, including holistic powders added to her food, nothing seemed to help until I tried OraPup. Her breath is getting better but the best part is that her back teeth are also getting cleaner. No more fighting with the tooth paste and brush. I recently visited my "granddog" in AZ and he loved Orapup, so I'll be ordering one for him!
