I brush their teeth - gotta love that beef flavored toothpaste (EEEeeeww!!). Don't worry, you're not a bad mother. I had no idea you were supposed to do this untill Biddy was about 10 months old! Who knew?? We never brushed my dog's teeth when I was growing up (then again, that explains his horrible breath!). I have a Winnie the Pooh kid's toothbrush that I use & beef flavored toothpaste that I got at Petsmart. It's not too hard to do, just lift up their lips(?) and brush away. Wait until you see the crap that comes off - it's gross!!! Good luck
