Mite

If this has any meaning but seattlesetters has a good reputation around this area. They are the prominent breeders of setters on the westside if not the entire state.

As to your problem, it seems weird to me. Perhaps, something negative happen while on tile? It could have been raised outdoors by the breeder so anything new could be strange. Hard to tell which over the internet. Talk to the breeder if this has cropped up before. One solution is to keep the dog outdoors.
