Looking for recommendations for a vet that is known for good chronic pain management. I have a 4 year old boxer that limps almost daily and our current vet has taken x-rays and even put him under anesthesia to do some testing on his back ACLs and everything has come back inconclusive. I'm looking to get a 2nd and possibly 3rd opinion as Duke is far too young to be limping like this. Thanks in advance!
