Have a feeling Claudia may get a few flames for her "Bite back" solution for
too-hard nippers.  I can only say that I used the exact same method on
Footch, my wild man, and it worked.  [Have to admit I discovered the method
in anger - a really sore toe and a scruffed woozle; nipping back seemed
natural].
 
Footch hasn't been intimidated at all, still nips and plays, but he got the
message: not too hard.  Or at least run like crazy if it is too hard.
 
Were only all problems as easily solved.
