I've taken my dog to Pet Daddy 3 times, only because it is convenient to my house. They're water temperature fluctuates, you have to lift the dog into the tub (not easy when your pooch is your size) and their incredibly loud dryers are ALWAYS on. The dryers put the dog on edge, making the task tougher.
That said, they do have quality shampoo and treats, decent hours, and are conveniently located.
If you can, try rub-a-dub dog on Phinney Ridge instead.
