I take mine to America's Country Store. Highly recommend Jessica and Sam there. Wiggles and Wags is also good.
Jessica was at Wiggles for a while but is back at ACS now. Sam is the grooming manager at ACS and she almost always books up a week in advance, so make sure you call in!
I don't go to Wiggles anymore because the owner treats the employees poorly, but the girls there are good at what they do.
