Oh, Mike - I am so sorry this happened with you and Eddie - I can hear how much it bothers you. Not to downplay it at all, but I just wonder with everything that Eddie has had going on physically if this was out-of-the-norm for him, due to his not feeling all that well. Not to excuse the behavior, but it might explain the extent of it a bit. And obviously, he didn't realize it was *you*, like you said (not that you want him to use his teeth to that extent either way, though).
You've already gotten some great advice. There is another member on here who often helps with training issues - and she is a trainer - she is ScootieBootie - you really should PM her (she even has the offer to help in her siggie). Another one is...I'm not sure I have this right though, k9Trainer. Good luck - I know you'll get this figured out with dear Eddie!
