Whenever she looks a little scruffy...hehe I try to get to it every week but it sometimes turns into every two weeks. She's an indoor dog so she stays relativley clean!
BTW she loooves to be groomed. She'll stand on the counter where I groom her and she'll just look at me and stand still..she's such a good girl!
And I really think she enjoys the way she feels after her bath..she'll run around the house like a mad woman and then calm down, too cute!
