Next step, I would say, would be to get a second opinion. This sounds like somthing abnormal for a simple anal sac drainage and rabies shot. I used to work for a vet, and never saw the types of symptoms from what you describe. Blessings - Blu
I would get it in writing ASAP what they did with your dog, Then i would get a 2nd opinion, if its true I would get a lawyer because that dog will need a LOT of physical therapy and poss a wheelchair!!! Squeezing an anal gland wont hurt a dog unless they were rough with it!!
