Hiya JOEB,sorry to hear about your dogs leg. firstly im no vet but i can speak from experiance. i wittnessed a greyhound break its leg, as it was a coursing dog the owner thought that it wouldnt be of any use so was about to put it down,cut a long story short a family friend took on the dog along with all the vets bills. this leg was plated and the dog was soon on the mend. as for will your dog work again? cant see why not. as for the grey hound,well it made a full recovery and went on to catch many rabits for its new owner, ok it limped a bit and more so as it got older, but hay, dont we all?
