Carolina Gardening: Oh no it's truffle eating season, 1 by CoreHHI

No idea what this dog is eating but it happens a couple times a year. He digs little holes in the back yard and eats something. Last night he was outside for a good hour and when he came back in he was fired up. It's annoying especially at night, he's outside for a long time and when he gets in he runs around and barks. My other dog doesn't eat whatever this dog is eating. Doesn't stop him from joining in the chaos.

Anyone have a idea what he's digging up? I'm assuming fungus of some sort.
