You might try giving Olympia kennels in NH a call. They currently have a litter of 6 pups that will be ready to go at the end of May. One of the females is a long coat, and the last I heard 2 of the 4 females were still available.
They have both the parents on the premises, and, if you go on Saturday you may be able to meet a puppy from a prior breeding of these two dogs, who does training there. We're getting one of the male puppies, so obviously I think this is a good breeder and we like their dogs. The female is from the Kirschental line, and the male is a large WGSL dog.
