as said above a dog is worth what someone is willing to pay...
I bought a pup about a year ago for 500 bucks and was told by a few of my hunting buddies just how stupid i was.. now the same buddies have offered me twice what i paid for the dog... go figure
I wouldnt take 4 times that amount for him now.
if someone wants to buy a high dollar pup unless you are managing their money it should be of no concern of yours
