I take Merlin to our local dog wash every other week. I pay $12.00 per visit no matter how long it takes.They did try the by the 1/2 hour and most of his cleints are larger dogs so he started the per visit. He also has wed afternoons that he will wash them for you same price. It gets a lot of the older ladies and smaller dogs in. He provides the stuff and has moore for charge of other than basics. I have a special shampoo for Mrelin so I don't use his. Seems like hes doing well, carries lots of other pet products.
A dog wash and portrait shop sounds great. I'll see if I caan find his card .He'd be worth talking to. I'll PM you tommorrow with it. Going to bed had a long day.
