How on earth do you go about brushing a dog's teeth? Ever since I had to force hydrogen pyroxide down Maigee's throat (she ate stuff she shouldn't have), she won't let me do anything with her mouth. I want to train her to get used to it again, but I'm not sure how to do it. I thought brushing her teeth with some nice tasting dog toothpaste would help, but it hasn't seemed to do anything except make her run away. Any suggestions?
