Mine just hunt gophers.....the area in between the house and the trees towards the back, about 100' away or so is nothing but tunnels and craters. And the occasional feral cat. After they ate last night Red, he is 12 years old, went out and picked up the scent of something. Course it was just after 11 p.m. Calling him was useless. Had to go get him. He was running thru one section of the yard, nose to the ground barking. When I finally managed to get close enough to him I had to tackle him. He was so focused he growled & snapped at me. Glad we do not have any noise ordinances and I have some neighbors that don't mind the noise.....
