I had the greatest groomer in the world and she was so great. She did take about 3 or 4 hours sometimes when she was really a mess, but that was because she would bring her dog in and they would play with mine. So it was kind of a play date and groomers. I never had any problem with it. The only part Tinkerbell hated about it is when I would leave and once I left she would be fine and back to herself.
I was very said when the doctor told my groomer that she could no longer do it because of her shoulder.
I would try to find someone with a small business that just does it for the love of it. I wish I could have my groomer back. I groom her myself because I do not trust anyone like I did her.
