My 12 year old German Shepard Ringo who has arthritis and degenerative myelopathy started to feel good after first few doses. More energy, calmer in the better mood. He was feeling really down having really hard time to move. I also recommended canna pet product to my colleague who has golden retriever and he was so thankful for it! It’s priceless when you can relieve pain for your best friend. Thank you canna pet!
