Thanks for all the advice, its his front out side toe which is now slighty flat and pointing upwards, he is a smallish (23inch) light dog who is very quick so I'm hoping he will run enough to have the odd rabbit, even if not he will be a pet for the rest of his life, or my little ferreting companion. I will start small lead walks with him in a few weeks.
Its the dog I feel for he is so bored and restless, he's always been kept fit!!
Bloody idiots smashing bottles on fields if I knew who had done it they would have a hell of a vet bill to cover!!!!
