My idea of a good dog, is also, one that can do the job it was bred for. That has come from a line of dogs, that also were capable.
And i love the idea that you return a faulty dog to a 'breeder'. And them having to ensure they have room for their returns.
Last night i visited a friend, who got her DDB pup she's been on the list for for months. Paid $2600 for a female. And it has 2 major confirmation disqualifyers. Seriously, ripped off mate. Gorgeous pup, but a waste of money.
