I love threads like these and reading about everyone else's dog!
Cali is... pretty quirky, so let's see how many quirks I can think of off the top of my head. When she gets really excited, she scoots around the floor by running then sliding her feet out in front of her. If there's a blanket on the couch (or if she's in bed with me), she insists on burrowing herself underneath... often just leaving the tip of her nose out. Whenever she meets people, she rolls over on their feet... not by their feet... on their feet. She also hates walking in the rain and isn't a fan of swimming... yet she loves mud and tears right through it on hikes.
Her newest quirk, which is sort of annoying, is that she can't accept that she's done her meal and she now stands at her dish, staring at me, while letting out pitiful little yips. I recently switched her to Primal and she's gone from a dog who would barely eat to a dog who devours her meals in about a minute... which I'm thrilled about but I think she will take a bit to realize that she only gets two meals a day.
