Larry,
Interesting story about your encounter.

I often have said that it is not the dog but the owner that is the cause of the problem.

An excellent defensive tool for those folks who cannot carry heat or a blade is the FAST STRIKE Defensive TOOL.

It was developed by a father/daughter team out in Montana.

It can pretty much be carried concealed or even out in the open anywhere w/o causing any attention.

I have given a few to women doctors,teachers and relatives.
