I can't speak to the professional grooming service here. We come to use the big ol tubs, since our Corgi is the Anti-Drano.
It is a great place to come for his monthly scheduled baths, as well as when we take him out to the dog park and he finds the only freaking puddle in all of las vegas, and rolls in it til his white bits are black, and I don't even want his muddy body anywhere near anything else I will have to clean.
They have huge tubs with ramps up to them, a handy dog tether, towels, shampoo, and waterproof plastic apron, to cut down on the joyful Sud Shakes. It's a place you can plan for, and a place for emergency baths.
It's very, very cheap; $10 a wash, the staff is friendly, and they are conveniently located across from Mud-Bowl central
