You take your chances at dog parks. Dogs start running around and the pack mentality really takes hold. I have seen very timid dogs become much more assertive in that situation. Interesting to watch really. Lucky for us our dog park is segregated by size, under 40 in one area and over 40 into another. Our Scout (Maltipoo) weighs no more than 20 lbs soaking wet. Some owners are very responsible and 'manage' their dogs while others will sit there and laugh as their dog terrorizes the others.

Like most here I would have gathered my dog and left the area. Pulling and using a gun is flat out ridiculous. Lots of videos of Pit Bulls going sideways in a hurry so I understand the concern. That said the guy should face some sort of penalty for sure and perhaps lose his gun till he completes some anger management sessions.
