More: This dog is amazing. He has had cancer. He has torn both ACL’s in his back legs. He has triumphed over a stroke and many many other illnesses. He has eaten Purina Pro Plan his entire life. He has eaten Bright Mind ever since it came out. I saw such a difference in him afterwards. I swear by it and I truly think it has kept him young. He is about wore out but he still takes his daily walks and always greets me with a toy!
