I just went through the same thing trying to find Great Pyrenees. I found a good breeder of quality show dogs and decided to walk away from her because she wanted enormous fees for the dog and then wanted to control me and my newly purchased dog. She wanted her cake and to be able to eat it too.
In the past few months the "show ring" has left a bad taste in my mouth. I don't believe purchasing a dog from someone who shows them gives anyone any guarantee that the dog will be healthy and as pointed out previously in this thread the chances of inbreeding are greater, hence greater change of genetic malfunction.
I am now asking myself what these show breeders are really doing for the breed. They are not allowing puppies they send out to be bred but low and behold if they want to produce 6 (as mentioned earlier) litters from ONE female dog at their own hand "well that is different than irresponsible breeders" How is it any different? Not all the pups will meet confirmation, many times none of the pups are show quality and they send them off as pets asking EXTREMELY high prices for a pup that they dont feel are up to standard. Why are they charging these outrageous prices for a dog that does not conform? Not to mention they are selling LGD's and other dogs that have no business in an apartment in the city (as pointed out earlier), as a family pet etc. The dogs we are talking about here take enormous effort on the part of the owner to train and keep from boredom.
It is so they can continue the HOBBY they have enjoyed for themselves, not the poor animal they are carting around. This is the epitome of irresponsibility!! Why are they producing those litters? Not to be used as they were meant to be used, NO, HEAVEN forbid if their working dog actually works and gets the coat all messed up! They are breeding the dog to prance around a show ring for heavens sake. I have more respect for a person who produces puppies to actually be used for what was intended. A show ring is so beneath them.
Most of the time their dogs are left in cages between shows so the dogs are kept in pristine condition. IMHO this is no better than dogs being crated by irresponsible breeders. IT seems the breeders are out for the human condition and not the canine.
I can guarantee that the dogs I got from a farm with working parents will do a better job than the dog the breeder had in mind for me. The main reason is this breeder was going to sell me a 6 month old puppy for guard. If she was really interested in helping me in my situation she would have known that I would need a younger pup to bond to my livestock. It was my responsibility to do the research and find what I needed.
OP, you will find the dog that is right for you and on your terms in time, don't give up. It took me a while but I found what I needed for my situation.
