Did he put him on any anti-inflammatories? Back injuries in dogs is tough. My dad just put a big pup down for this very thing. It got to the point that he would holler over the slightest movements. I would try to keep him comfortable but confined. Walk him on lead to use the bathroom etc. I wouldn't want any aggravation and I would use anti inflammatories and DMSO. I LOVE the DMSO for myself and my animals. It's worth reading up on. I would also be messaging him a couple times a day. There animal chiropractors that might be able to help or make some better suggestions. I hope he gets better.

DMSO was once manufactured by Gaylord chemical Corp right here in my home, it was as common as tap water when I was growing up, my paw paw ran fox dogs harder than most and would wrap ace bandages around their joints and soak them in DMSO, there are still folks who have drums and drums of this stuff stored away, I stil have several several gallons stored in quart jars, folks around here used to mix it in their coffee as a sort of snake oil cure all, a horse chiropractor may be able to help you out....
