you, too, can find yourself taking a dog with a hurt elbow to the vet and being told it'll cost £1250-£2500 to fix. 
I had the worst night of my life after getting this news.
In fact, the deciding factor was less the money and more the recovery process and time, and the likelihood of it being fit for work afterwards. Having to keep a working collie on a lead for three months, on the farm where his pen-mate is then doing all the sheep work, and then not being sure the bionic elbow would be up to the workload of doing real work... These dogs live for work. I couldn't imagine Skip being happy in a life of forced retirement, when he felt fit for work in himself.
I'd been told that if I didn't have this bionic procedure, I would be dooming the dog to a lifetime of arthritis, so the decision was a truly horrible one to have to make.
After a sleepless and agonising night, I called the vet to tell them I would come in and say goodbye to my injured pal.
By the time I arrived, one of the older, wiser vets, one on the farm practise side, had an alternative offer for me.
Skip came home with his elbow missing a bone from its innards. Lead walks only for a few weeks, but then gently back to work. That was a good few years ago.
These days, in cold, wet weather he does sometimes limp - and sometimes doesn't want to run about very much. But there are drugs he can have to help with that, and he's continued to work, albeit more steadily now that he's 12 years old. Which is pretty impressive for a collie that's worked on the hill all his life, in my book.
I often wonder what the outcome would have been had I had pet insurance. Would I have unearthed this alternative, much cheaper and much more easily recovered-from operation, or would Skip have had the bionic elbow, had to be on lead walks for months - and would it have withstood the stresses of work, after that? Or would I have reached the same conclusion, and thought it better he didn't have to go through the op and recovery, with uncertain outcome for working afterwards? I really don't know. But I am sure Skip is better off with that little bone missing and having had another 6 years productive working life.
