The other day, Cotton begged and begged to go out for a "walk". Every time I turned around, he was running for the door or doing his funny little hoppy dance that he does when he wants to head out. Finally, I put on the sling, popped him inside and then took the dogs out. We were out for an hour, but it was maybe only 5 minutes before this happened:
The Dude fell asleep.
And he stayed asleep until about 10 minutes after we got home.
