I agree with what Mite said that most is man made. I had an Irish
that was almost gun shy. She was very timid and took alot of work.
What had caused this was being in the cargo hold of the jet liner.
There is alot of load noises from the wheels being lifted as well as
breaking on the ground. Also cold and dark in there. She came
around after a while. But, it took alot of work being carefull and
keeping the kids from banging caps, and etc. After chasing birds
for a while I decided to try and shoot a bird and now when the
gun comes out she can not wait to go hunting. She loves to find
the birds and shooting them does not seem to bother her none.
