That’s extremely unfortunate. Of the many many dogs I’ve come across, big & small, including a few strays that I was unwise to approach so casually, I’ve never been bitten or attacked. Perhaps I was merely fortunate. Knowing what you’ve gone through, your stance is understandable, although I don’t entirely agree with it. Yes, all dogs in public should be leashed, although I find it unnecessary to put a muzzle on all but the largest dogs who have the actual strength to cause serious harm. I definitely don’t agree with any sort of licensing or routine inspection for dog owners, but I get why you would think this is necessary… perhaps its best if we simply agree to disagree.
