I floss my pup's teeth. I use these things called "Plackers". They're plastic sticks with floss on the end. I only use them on my girl though - and on a few of the bottom teeth, not all of them. She chews the rug under the dining room table & sometimes the rug fabric gets caught between a baby tooth & a big girl tooth. If I don't use floss, it ends up getting stuck & stinky. So I guess that two of us are crazy
