Maggie is an Australian Cattle dog and about 14 years old. She has been the best guard for my property. As she has gotten older, the arthritis has set in and made her stiff. It was actually quite scary how quickly she was having trouble moving. I could see that mentally it was effecting her the most. When I started her on the Canna-pet, the relief started immediately. It became quite clear that she was getting her ability to move back, and it helped her temperament immensely. All I want is for her to be as comfortable as she always was, and this does the trick. I tried other brands, as I can get locally, and they aren’t comparable. Aside from being more expensive, it didn’t seem to give her the same relief as the Canna-pet Advanced did.
