I am not sure if the Buhund is in the USA in any number, in the UK there are fewer than 50 bred a year. You may find you will have to look at similar breeds, like the Norwegian Elkhound, and some other medium sixzed Spitz breeds, though a lot of them have more coat than these two breeds.
Contact the AKC for details. If you put Anerican Kennel Club in a search engine you should get their very comprehensive site. This site is UK based.
I can give you the email address for a lady who breeds Buhunds in the UK, she is quite an authority on the breed. she may well know of the US/Canadian position, and certainly will be able to give you plenty of information.
