Had this dog this once, he'd stand under the table, just stand there knowing something was going to drop. Someone'd get up, get something from the fridge say, he'd glance up, lick his lips and go back to watching the floor. You had to be quick or just abandon all thought of ever getting anything back once it was dropped. He'd be on it. He was a firm believer in the 2-second-rule. Anything dropped was his! But otherwise, I thought it was ten-seconds...poetic license I think, once you reach a certain age.
