I love Google search!:
It looks like Louisville is going to be your best bet:
Moochie & Co. The Pet Station Salon & Boutique Barkstown Road
It doesn't look like there is anything in E-town except E-town Pet Center, which is a mill seller, so definitely a no-go.
There's a Spoiled Rotten Pet Boutique in downton Lexington, but I didn't really find much info on it. When I'm in Lexington, I spend most of my time around campus, so not really a lot of help there. Sorry.
