time is a great healer mate but as with some injurys they cannot be put right keep him off 4/6mths with treatment
then take him back to greyhound vet before any strenuous excersie I had one that was stictch back but dog was never the same
I mate did a keeper called Richard have the dog or does he belong to you as I have a bitch supposed to be by him any details would help pm me if easyer
a lot of dogs produce good offspring but ive also found the stud dog as to go to quality bitches to regually produce good dogs
ive seen good dogs go to mediocore bitches and end up with second rate pups then the stud dog gets the blame
