My three get washed
once a week, unless I am going visiting with them....then they get spruced up if they haven't been washed for 3 days or more, or unless we have been in woods (twigs, mud and lychin in coat) or on the beach !(all that awful sand ruins their coat.)
My two girlies are long-haired to the ground, and my wee male has also been long, but lately has been clipped short as he's bad for peeing on his curtains....so it was better to chop them off than continually washing his legs, etc, every time he was out for the toilet !!!
