Nugget, it's never the pup's fault if there's something "funny" going on. Is there a change in your life? You're definitely sending your mom a message. You must really love your mom and just want something of hers for your very own! Or maybe she went somewhere reallllly interesting in the shoes? I don't like it when my mom goes out without me. I'm her Davy - I should always be with her!
You know that old saying about how pups and their bipeds start to look alike, the more time they spend together?
I'd say Mom and I are spending just the right amount of time together, wouldn't you?
I think you just miss your mom. Your mom is the bee's knees! That's my professional opinion as a mama's pup. Woo. I hope this helps, Nugget!
