This is Sam (hopefully that's self-evident!) and George, from my story "Georgie-Porgie, Sammy and Me."
Here's the part that inspired the drawing:
“What the?!” Sam reached into the brown-paper grocery bag and pulled out the puppy. He held it up, face to face, and the little dog yipped and wiggled, its tongue flapping in a futile attempt to slobber all over Sam's nose while its little corkscrew tail beat against his fingers.
Any misgivings vanished then, because Sam laughed. Not a grin, not a wry chuff, not a short chuckle-- but a full-on, eyes-crinkled belly laugh. How long had it been since he'd heard that?
Art under the cut!
