I am so sorry that you had to deal with that, William. I also would have been very angry, and probably would not have held my tongue like you did. She was angry and wasn't able to control the situation, so she blamed the other person/dog. She was wrong. We know that Snowy is not a viscious dog. She is a star. That lady will feel mighty silly when she sees Snowy at Cruft's next year.
Give that pretty girl some hugs for me.
