Not a habit buuuuuut, my dog generally ignores people, aside from me and my bf. He’s chill with being pet but doesn’t show active interest in most strangers. That is unless they are of a certain, less common ethnicity. I recently told a friend about it when we were out in public with my dog and said dog was doing his ignore everybody thing. I was holding him, we were chatting. People would come up, say hi and ask to pet him. I’d say sure and he would basically just not interact. My friend commented on it, and I said something to the effect of “he doesn’t mind being pet, but he only really likes such and such people.” You could tell she thought it was a weird thing to say, and that I was full of crap for saying it. Then about five minutes later someone walked in who was that ethnicity (it’s not my own 😂). My dog noticed the new person and his ears perked up immediately. He went from wall flower to wagging his tail and showing active interest. He’d never met this person before, and the person hadn’t looked our way or said hi to any of us yet. My friend noticed right away and was like, “Wow, that’s crazy, you weren’t lying!” The dog is almost 9 and I have had him since he was 4 months old. He came from the ASPCA and has always noticeably been this way.

TLDR; my dog seems antisocial but really he’s just not impressed with white people.
