My little yorkie is about 10 weeks old. I brush him daily, but he loves to play with cats, dogs, puddles, and anything else he can find! He is starting to get a little greasy. I'm hesitant to bathe him because my Yorkshire Terrier book says to only bathe puppies in exceptional circumstances, but I miss his soft clean coat! I'd love any advice on whether he can be bathed yet, or if I should just grin and bear it. Thanks!
