Maybe that is because it is fall.
Our male dachshund has been full mouse alert for the pond area in the back yard. When he is out there in cold weather, it is a real mouse alert. I set three traps on the open ground out there Tuesday night. I got two of them. I set three more last night. I came up empty. Either they learned real quick, or they moved on. I will try again tonight.
We have to lock the side gate to keep the dogs out of that part of the back yard when the traps are out. I don't need to catch a dog's nose.
