Dessie is quite right Zoe - it is very unlikely that any reputable breeder would be interesting in using your dog at stud. Could you tell us why you want to breed from him? If it's because, you would like another puppy just like your dog, then it's far better to go back to your breeder & buy another puppy from the same lines. You would not want to risk your dog's personality changing I'm sure - what they've never had they won't miss :wink:
