For some reason this dog will not allow me to brush her teeth. I love her. She is fluffy, she is cuddly, she is playful, she is very nice. But for some reason she just will not allow me to brush her teeth. Do you have some suggestions? I know. Put some toothpaste on the finger and rubb it on her gums and stuff like that. I have already tried and tried and tried that. It is not working. If you have some pointers for me, let me know.
