Have you considered going to a self serve dog wash and using their higher pressure water and dryer?
I also feel you are washing your dogs too often. You can give them dermatitis if you wash too often, they also will smell worse if you bathe too often.
I would google for your breeds how often they should be bathed. For instance, it's recommended that a GSD be bathed every 3-4 months. Some dogs can be bathed once a month.
