it's the poor suckers who buy in a big pup, adolescent, young adult that hasn't had any time spent on it at all. They are either misinformed about the dog, or don't realise what they are taking on.
And most of the time these so called "poor suckers" dont have a clue about dogs and just buy on a whim!! the same ones that if given a pup would mess that up too and turn it into one of these big pup adolescent dogs we see for sale all the time, anyone with an ounce of dog sense and know what they are doing wouldn't get into this situation, but then again as has been said over and over again.
