Sorry you are going through this. One of my dogs was limping (foreleg), so I took him to my local vet, he took x-rays, diagnosed elbow dysplasia and recommended surgery. Long story short, several things happened at that clinic that caused me to doubt the diagnosis, so I requested he send the images to a specialist, and I got a second opinion from a more qualified vet (and a 2nd set of x-rays as the 1st were badly positioned). Turns out, my dog just had a sprain. Even if your vet is a specialist and the diagnosis isn't in doubt, it couldn't hurt to get someone else's perspective on the course of treatment. Wishing you the best. Keep us updated.
