Don't feel bad. My dog is 7 weeks old and totally turns into a possessed animal at times. Her biting is Waaay out of control. I can't do anything with her. Like you, i've tried the can, i've popped her nose (which makes her worse) and now I'm trying ignoring her. But it's REALLY hard to ignore her while she's trying to detatch my baby toe.
