He went out a while ago, and hasn't come back. Usually when I call him, he shows up right around the corner, but this time there's no sign of him. His health has been a bit iffy lately, and I worry about him being out after dark.

UPDATE:

Found him! It was so dark, I could barely see him walking in front of me. Had to carry him (he was covered in so much dirt and stuff!) all the way back from halfway down the dirt road. Oof. Too much activity for one day with my ulcer. At least we made it back safely. <3 That's what matters.
