Well done you and that dog I bet your made up mate BUT don't over do it as the dog's still a pup at that age and you don't want to spoil it. Take it easy for a few month, too many people want to rush in at such a young age and you could end up ruining a potentially good dog. The dogs got a taste for it now but my advice to you is to just let him watch for a while, keeping him keen but don't be tempted to run the dog....
