What is this wonderful, all-natural treat that dogs just can't get enough of?
Sheep poop.
As soon as they step outside, the dogs have their snouts to the ground, sniffing around trying to find sheep poop. They'd spend all day out there if they could. Snow doesn't stop them, they just dig down to find the tasty morsels.
It kind of makes the dogs look like sheep, grazing on the lawn. Except instead of eating grass, they're eating recycled grass.
