Fritz, a schnauzer, is groomed at least every five to six weeks in the warmer months, and I bathe him once between that period. In the cooler months he might get groomed every two months because he is cold natured, so I try to bathe him at least twice a month. He hates the bath, but he likes the long walk afterward to air dry. He is a very clean dog so I don't feel the need to bathe him every week. HTH
