Sorry for the formatting guys, on mobile right now. So this really pissed me off today that he thought I was in the wrong, until I realized to me my dog is the cat's pajamas and probably he feels the same for his. So the chances of either of us being objective here is minute, wantes to get some imput from you guys. 

Another dog latched onto mine(Bo) and was chasing him around trying to hump, which my dog doesn't put up with. So Bo lost his patience since he couldn't even walk around with this dog repeatedly trying to mount him and started posting up this other dog. This always has scared me with owning a pit mix just because of the stigma around the dog honestly and had the other guy eyeballing mine like he was dangerous. 

So the other dog owner comes up apologizing saying he thinks he's playing, but can't keep his dog from mine. He just would run around and jump right back on Bo. The other owner had to leave because this didn't stop. But called me the asshole for bringing an 'aggressive dog' to the park. 

My main defense and why I think the dude is WAY out of line is one humping is not JUST a play behavior. It's about dogs asserting dominance over one another. And when your dog is trying to hump mine to that extent, you need to better train your dog before he does that to a way more aggressive dog than mine. And two, my dog may be the one getting angry and loud, but your untrained dog is provoking this. Or what am I supposed to do? AITA?
