We have been using Canna-Pet for just about a month now. My cousin had told us about it after seeing it used on her stepmother’s dog. I use it on my rescue, an American Staffordshire Terrier, Rex, for his shoulder. He has significant arthritis in it. He is only 8 and used be a very active dog. We were using a prescription pain killer from his veterinarian to help ease is discomfort (Trammadol). Going for walks, playing with other dogs and stairs would set off flare up and before you knew it, he was up to the maximum of 9 pills a day. Since the use of Canna-pet, he gets maybe one to two pills A WEEK! He is playing like a puppy again and able to enjoy long walks once more.
