I'm Not Missing by Kashelle Gourley and Skylar Hogan

Humans don't realize the stresses of pet life.
Working hard to meet every command.
Trying to be a good boy, the best boy.
It's exhausting . . . humiliating, even!

Sick of the pressures of pet life—the costumes, the treat-withholding, and the dreaded cone of shame—one dog escapes to fulfill his true Lone Wolf destiny. But then he sees his owner—um, ex-owner—with a new dog and feels unexpectedly jealous. All he wanted was a little space to poop in peace, not for his ex-owner to forget him entirely! Is it too late to go back, or is he stuck in the doghouse forever?
