Oh Jan you must have been scared out of your wits! And your poor doggie. I think you should have said something, it sounds like (not wishing to scare you in any way) that if your hubby wasn't there things could have turned out a bit differently. Imagine if that had been a small child. I think I'd report it. But regarding going out again, is there another way you could walk? Maybe spraying the animal could provoke a reaction.
I hope you feel better after your shock.
