You can’t go wrong with Chad’s dogs at Willow Creek Kennels. My brother has a dog from Chad and if I would have been looking for a GSP instead of a lab I wouldn’t have gone anyplace else without hesitation. Here is a link to his site. He has many started dogs as well. Tell him that Nathan sent you. He is on the high side but when you ask around he will be on the top of most anyones list. Remember, you get what you pay for and the starting price of a dog is a minimal part of what a dog will cost over it’s life. A couple of links! Good luck on your looking!

Link to some of his videos on you tube. He is a very good trainer. My dog will be going there in a couple of months.
