I brush Layla and Jake's teeth twice a week, Wed. and Sat. I use a doggy brush with an angle but am going to try kids toothbrushes instead. They don't seem to mind it, they're used to it, Jake actually likes it. I don't brush Lacey's teeth because I like my fingers. I did try when Lacey was a puppy, she was just too wild. She just doesn't like to be messed with, never has.
