I personally do not like the looks of their dogs. They health test which is good, but I find his dogs to be light years away from standard. My long coat girl Athena is from a stock coat parents. If I was going to get from a long coat breeder I would not choose pioneer. My suggestion is look for a good breeder and ask if they ever have long coat pups. But if your set on long coat breeder check out kelly peet or schlossfelsen kennels.
