Colt, the same thing happened to me. I recently got her groomed and I expected the same thing I got last time. Well I got more than I bargained for, and that is the exact same word I used: Crushed. Tosca's beautiful mane is a shadow of its former self. I was horrified and am just now getting used to it, after nearly two weeks. I never expected them to do this and I was absolutely speechless when I picked her up, if you can possibly imagine me being speechless. She wasn't matted and all I asked for was a bit of thinning of her butt hairs, the hair between the toes trimmed, stuff like that, same as last time. They stipped her undercoat so that I can actually see the skin when I move her hair on her back! All that beautiful fur she had grown in, foiled. Apparently, this kind of grooming is just what most collie people want, well I am not one of them. I was horrified and I know just how you feel. I can't even find a way to fluff the hair on the sides of her neck to give her a mane look there again. Just terrible.
I only discussed this in PM with one person, I was so upset I couldn't even post about it till now. I am STILL upset and prefer to pretend it didn't happen.
Edit: I didn't realize this wasn't just posted. It was bumped by the previous post. But it's the truth so I finally said it. There you have it. The groomer ruined my dog.
