That may be the case, and certainly you're entitled to your opinion. There are a number of people with $3,000.00 who disagree with you, enough so that they've gone back to New Skete for second and third dogs.
Sure, they had a great experience and wished to have another one. On the other hand in my particular case, I have never paid a cent for any of my dogs. I was nothing short of lucky is all it was. The first one was given to us by her (my wife) cousin who had a dairy farm and along with the cows he owned some GSD. He had one left from a litter and asked my wife if we wanted her. the next one was from a friend of my daughter who was a local breeder (for show) and in a litter of 8 there was this "runt" which he was going to destroy because it was not a show quality animal. M7y daughter begged him not to do it and he gave her the dog without papers and she was a wonderful pet. Next we got one when i owned a pet shop (no dogs or cats) and had a customer bring a tan and black female in asking if I knew of anyone who wanted it. We had a Shepherd and a cat but I said I'd let my wife look at her and let him know. We kept her and she was also a great dog. Then my wife was offered a 16 female by a perfect stranger after she admired the dog as it was being walked past my daughters home a few years ago. It seem the woman was walking the dog for a friend and knew the friend was having marital problems and was moving to an apartment where dogs were prohibited. She said yes and it happened twice more in ensuing years. At one point we had 3 of them at once. My belief is having a gentle sweet dog as all of ours were is wholly dependent on the love and affection the owner shows them from early on. Tat and the proper socialization of the animal among people and other pets. The only crap shoot is the health of the dog as it gets older and as long as you take proper care of them and see to their diet it's a matter of genetics after that. Paying $3000 may get you a great animal for sure, but it also may not while paying $1500 0r even zero cam also get you a great animal, or not.
