I thought I had heard it all!! This woman sounds unstable. No wonder her dogs weren't show quality, she probably doesn't know the difference. Owning two yorkies doesn't make anyone an expert; unfortunately, anyone can buy a yorkie, or two, or God forbid three or more. I can't see this being just a lapse of judgement; if she is a groomer, she is aware of how protective owners are of their dogs hair. I feel this was a deliberate, petty act of a jealous woman that was certainly no friend to you. Give your precious baby extra loving, I would imagine this so called groomer was not as nice to him during the "grooming" as she could have been. That said, your boy is gorgeous!! His little face is so perfect
His hair will grow, and you have seen the true colors of your so called friend; you are lucky to have her out of your life.
