When I was a teenager, I had an Italian greyhound who would collect fallen apples from our tree in our back yard. He'd make a pile and leave it for a week or so. Then he'd go out and chew on the apples before running around the yard at full speed until he passed out in the sun.
Once we figured out what he was up to, I'd keep an eye on him so I could go pick him up and lay him inside on the cool tile next to his water bowl when he was done for the day.
