Riley has two "aunts" - my parents' dog, Chloe, and Josh's parents' dog, Nikki. We didn't think they'd get the opportunity to meet, since Nikki lives in Phoenix. But Josh's family loaded her and Nana Wallace up for a road trip to the midwest over Labor Day, and the two got to spend some good time bonding.
While he isn't emotionally dependent on Nikki, they got along quite well overall. Which is to say they managed to nap on the same couch with little fuss.
