I love all the bandanas everyone has pointed out! I don't really have too many suggestions, but I can tell you that the darker bandana you get -- the better. I made the mistake of getting Zoey a light pink bandana and it was noticeably dirty after a couple days. And especially with summer coming around -- which means warmer weather for you Northerners -- the dogs will be outside a little bit more, which means more opportunity to get dirty.
