Charlie was doing a lot of paw licking so I took a look. There was something like abrasion between two pads. Julie and I applied some wound cleaner, neosporin and a bandage. Charlie wiggled a lot, yipped a couple of times and pressed his teeth to my hand, but did not apply pressure. Eventually he stayed quietly down while we had dinner.
Before dark, I took him for his walk. He hopped eagerly, at times on either of three or four legs, as he made his neighborhood rounds. His spirit was uplifting. I know he will be healed soon.
