I went this weekend to get my shih-tzu groomed at the Petsmart in Germantown, MD. As soon as a entered I did not feel wlecomed the groomer had such an attitude problem. After 5 minutes I recieved a phone call that my dog was "attacking" the groomer, as a result they could not proceed with the grooming. I told the groomer to place a muzzle on my dog, but she would refuse and then began getting an attitude with me. I was very upset since I had come all the way from Rockville and wasting all my time. I have never experienced such thing.
