Logan,
I used a mobile doggie groomer after I had knee surgery. The problem was that they didn't have their own generator and used power from my garage to turn the dryer on. Since the dryer was very powerful, they tripped the box every five minutes and I had to go to the basement to restore the electricity. Not a very good solution to my knee problems. Now I take Carina to a doggie day care place to be groomed.
I'm sure your girls and Zipper will look more beautiful than ever, if that is possible , after the shampoo and blow dry. Give them all a big hug from me.
