Cheeno, my beautiful 3 leg dog is now 13 years old and his back legs are starting to fail. We thought it would be his one and only front leg that would cause him problems in old age and had already planned a front end buggy for him but it is his back legs that are going. We know he is in pain (he is on tramadol) but I think we are seriously going to have to think hard about his future. It is going to break OH heart when we do. Off to the vets hopefully today if we can get an appointment, fingers crossed.
