My 14 year old Yorkie has recently been diagnosed with spine and nerve problems. He has severe pain in his back end (hips, knees, lower spine). The doctor gave gabapentin and he is already on carprofen. It seems he’s getting worse with more pain, and sometimes whining and yelping in pain even when nothing has touched or moved him. Is there anything else I can do for him?? I hate to see my boy in so much pain.
