My early warning detector was in full red alert, DEFCON1 mode this morning. Our male dachshund, Reuben was circling the storage building, and there was some sort of critter under there. I was mowing the yard, but when I finished I planned to set some traps, assuming it was mice.

He has helped find and kill a few of them.
This time I am thinking it was Bugs Bunny. As I was mowing along the edges of the storage building, he took off to the west part of the yard, nose to the ground, sent trailing. I think the sound of the mower was too much for Bugs, and it took off. Once Reuben figured out no more bunny to catch, he gave up and went back inside.
Reuben has actually caught and killed one dumb bunny. Reuben's does not allow any critters to share his back yard.
