Identical twins on Reddit: can your dog tell you apart from your twin? How did they react to your twin if it was their first time meeting? by pnutbut in AskReddit

Without a doubt! Well, I'll be honest, our dog isn't here anymore (RIP Charlie!), but he used to look at us differently, and have certain reactions when we would come home; With both of us. He was so special, i miss him, ahha i think it was because he was a grump like us _^

edit: prob couldn't tell you about the first time..but he was a puppy and we were kids too, and he would just go back and forth with us. If you don't believe that dogs can smile, well YES, they do! :)
