They've really thought of everything to make your self-dog wash experience as easy and fuss free as possible. You rent a little enclosed stall that comes equipped with a 3-feet industrial sink, which is high enough for most dogs not to jump out. There's even a mini staircase for your dog to walk up into the bathtub/ sink! You get a short leash that clips onto a hook in the wall so that you doggie only has 5 inches or so to move around, which will make it easy for you to hose him down. You get an easy to use hose spray for the water and a pressure sprayer than shoots out instantly sudsy shampoo, so it's super easy to create a lather.
The best amenities are when you dry and groom. You get a grooming table to stand your dog, and an industrial dryer than blows high pressure cold air, so you won't ever burn him. Of course, he'll be wiggling around and won't like it, but after a few trips he'll get use to it (and he won't have a choice because he's strapped down on that short leash!). They also provide fancy pooch colognes (organic lavender, green tea) as well as Q-tips and alcohol to clean out the the inside of your doggie's ear, something I never even knew people did before I visited UShampooch. You can also ask for clippers and a comb to give that coat a trim. I usually spend a lot of time cutting out knots and matted parts, and being able to trim my dog while tied down is a godsend.
After the hard work (it's tiring for your pooch to be standing too) they give biscuits for doggie and candy for you. They also make homemade dog cookies there! The people who work there are generally very helpful and will let you know the steps to groom (brush, then rinse with water, brush again, shampoo, towel dry, blow dry, brush again), so if you've never played groomer, this is the place to start. I also just love how when you put on one of those plastic aprons you feel exactly like a pro-dog groomer.
UPDATE: Lisa of UShampooch let me know that there is a groomer there available during the week by appointment and comes in Saturdays for nail trims and light grooming (sanitary trims, facial trims, etc).
