I guess I'm lucky because I can do 5 doggies in one day without much problem. It's warm here so I let them air dry, and my 3 Morkies are cut shorter, 1 silky Yorkie w/longer hair, and a schnauzer. I do one at a time in the kitchen sink, towel dry and let them run around and air dry, and do brushing and nails last.
Lucky because it takes only about 1 1/2 hrs. every Sunday, and a bit longer on days when they need hair trimming.
