Tim;
You are welcome.
I have never been a fan of pushing the hand back farther in the mouth way.
And yes, you are correct, that way wouldn't be good for the kids to do as
they could get hurt. Your 5 year old could be a big help, five year olds are always wanting to help with things. LOL So it wouldn't be difficult for you to
show your 5 year old how to teach the puppy not to bite. The 2 year old is
another story though, as you know.
