Hi S.. I have a 2 year old Shih Tzu and live in Montgomeryville. After a lot of trial and some awful error, we found a groomer that we absolutely LOVE. Her name is Staci and she is at the Best Friends facility in Willow Grove. It is a little bit of a trek but absolutely worth it. They are located on 611 between an Infinity Dealership and a Best Buy. Right near the entrance to the PA Turnpike. They are somewhat affordable ($50-60 with tip) and she does the most amazing job. My baby loves her. If you go, tell her Sarge sent you! Good luck.
