My English Mastiff, Voodoo, was having trouble getting up. She was very weak in the rear and being old for her breed and 175 pounds, she wasn’t able to get around like she used too. I started giving her Canna Pet last fall and the results were AMAZING! After just a couple of weeks on the Canna Pet she was running and playing like she was a puppy again! On September 7th, 2017 she celebrated her ELEVENTH Birthday running and playing in the yard! I HIGHLY recommend Canna Pet, it has given Voodoo another year with a great quality of life!
