My one dog koko, makes my grandma feed her by hand constantly, and she always starts to howl what we think is "mama" or "hello" whenever someone walks into the house, she also likes to eat tic-tac mints we use them as treats, idk if i agree with that for health reasons.

My other dog pipsey has so many quirks, he was the runt of the litter, we taught him how to walk on his hind legs, he has knocked dogs larger than him defore and then proceded to walk off like a bad***, he even picked out a pink rose to bring home to my Mom on one of his walks and then after he got home turned to almost smirk at my sister as if to gloat to her idk he is a weird one
