A few notes, since I don’t have much time to linger here today:

1. Actually, it’s the left foot he licks, not the right.
2. I imagine that some of his legs would be shaped like shoes and some of them would be duck feet and all of them would be flavored like bacon or ham or cheese or venison or salmon. A whole closetful of legs for him to lick or chew or whatever he wants, easily replaced, no steroid spray or antibiotics necessary.
3. This will probably be super easy elective dog surgery in the future. Can’t the future hurry up and get here?
