I would definitely say something to the owner of the store and because I have a big mouth I would have spoken up for that dog when I saw that happening- I would say something to the groomer. Also if possible I would try to find out who the parents are and let them know of the abuse going on there. You HAVE to say something and I would have a problem taking my dog there and supporting a place that employs someone like that. There are too many horrible groomers out there and since our animals can't speak we need to speak for them
