Right here's the script,my mate has a Lurcher that broke her hock 4 1/2 months ago, he had it reset and in a splint and cage rested her for about three months,he then started light walking her and has in the last two or three weeks started taking her out with the push bike, fast trotting her beside the bike. She is doing about three or four miles no bother and shows no ill effects after it. What he wants to know is,has anyone had a dog with this injury and what is the next step for the bitch?
