i just cried over a simple interaction regarding my dog and another. why do people act like this? or maybe i’m just sensitive as hell…?

came back from walking my dog & i open the door to get into the apartment hallway. at the same time another guy with his dog was going the opposite way of me and i scooped up my dog bc he is scared of other dogs and acts aggressive sometimes bc of it. since he’s small i just pick him up and walk before he can react. before i opened the door i stopped to move out of the way so he could pass me instead. i heard “come on!” all loud and somewhat rude, multiple times. i didn’t react or move because the tone of voice gave he was talking to his dog and so i figured his dog was being difficult so i waited. then he peeked his head through the door window & said it to me. so i opened the door to walk through. at this point the interaction should’ve ended. there’s no need to talk to me RIGHT? so then he says “my dog isn’t going to do anything to you!” and he’s on the phone btw, and was making a fuss about it (he was trying to come off nice but i just don’t like being that way with strangers bc it sounded like he was talking to one of his homegirls) his dog is a bigger dog but i didn’t even care, i have no stigma against big dogs lol. i went to school for veterinary medicine, i understand dog behavior and aggression. yet he’s trying to tell me about my own fucking dog and saying they won’t do anything but stare at each other. I KNOW MY DOG. my dog won’t bite your dog, but he’s mixed with chihuahua and will bark his head off which i try to avoid. i told him it’s not because of his dog it’s just because my dog does too much. and he used my dog just staring at his as an point as to how they won’t do anything but stare. if i didn’t pick my dog up he’d be barking and doing the most. of course he’s staring, bc i know my dog and did not give him time to act a fool. it’s a very simple interaction, but the loudness of his voice and tone of the convo overwhelmed me that i did infact shed some tears when i got back home. i know it’s not a normal reaction to have but i genuinely hate when people speak this way to strangers. am i being dramatic or no? i feel like people are way too comfortable talking however they want. also i kept walking as he was speaking, yet he kept going on in the same tone of voice which i guess made me feel heated and overwhelmed bc i genuinely wanted to leave the situation.
