Aren't they gorgeous? Presumably they are the heavy coats as you describe them as fluffy? My favourites!
I've met two, one was long coated and very skittish, the other I'd have given my eye teeth for, short haired, cool as a cucumber and handsome. I said to the owner " oh a Utonigan " ( as you do when you want people to know you know a thing or three about dogs ) he replied " Aye, but lets be honest, he's an expensive cross breed " I pointed out that any good dog was worth it's weight in gold.
