If a dog isn't any good, it don't matter how much time energy effort vet bills or feed has been thrown at it, it still isn't any good. If all the time and such pays off and it makes a good dog, then a person can justify puttn a bigger price on it. If all it can find is a food bowl, and you've put a couple or a few years into it, it is still only a feed burner.
x2...no matter how cheap or expensive a dog...there are only 3 types of hunting dogs... good to great dogs and culls...
