I have no personal experience with of a dog with this problem, but know of a mastiff that had OCD of the hock (treated via surgery) and also had a deformatiy that cause the legs to remain straight.
I find it quite amazing that he has not mentioned OCD,
(especially as Rotties are one of the breeds that OCD of the hock is common in). This will result in inflamation and pain of the joint and can be a completely different thing to the actual hyperextension. OCD may require surgery to remove the loose bits of bone/cartalidge.
I aslo am quite amazed that a vet can tell wheather the hyperextension of the hock is due to an actual skeletal deformaty and not slack ligaments, without doing any xrays, especially being that the joints are inflamed, which in itself will effect the movement of the joint.
Hyperextension of the hock as deformatity should only pose pain from arthritic changes, so would require the same management as any arthritic dog - PTS is only the way to go when nothing can control the pain or movement is effected to the point of effecting the dogs quality of life. The level of arthritic changes (if any are there) can be determinded by xray. It is possible to fuse the hock, (common after RTA injuries) if it can not be operated on.
Please don't feel hopeless, seek the opinion of an orthapedic specialist.
Buster had several growth problems as a pup, he was almost completely down on his pasterns, the vet said it would need opperating on as it was a deformity. The specialist or the breeder didn't agree. A change in diet (off puppy food, onto adult food), a careful' exercise programme, weight management and supplements of Glucosamine, have all worked wonders. At 5 months old Buster could barley walk 4 yards, at nearly 3 years old he can run faster than me and actuall enjoys pulling me up steep hills.
Buster also walked so poorly that the vet was sure he had HD, xrays & the specialist told a different story -his hips were fine.
So pretty much i have the same story as Katy H, joint laxity (from over-growth in the ligaments) causing an array of mobility problems, that were all sorted with time & management. And a
specialist that gave a different outlook than the vet!
