I think when it comes to pups although there's never any guarantees you have to work them hard every generation really test them, weather someone goes out once a week or 3 times a week it's each there own aslong as there living the good life but when it comes to pups be that gundogs lurchers farm dogs or any working dogs for that matter they should only be bred of tried n tested n someone who is breeding for themselves and anyone looking to purchase a pup should look no further than this any if there isn't what you fancy about at the time then be patient but to many people breed for the wrong
