Oso comes in this morning after some very active squirrel chasing. I say to him "did you get the squirrel?" He bolts for the door and is gone another 10 mins. He comes back in tired and in need of a few zzz's and I say "did you get the squirrel?" He again bolts for the door and is gone. Back and forth we went for at least 2 hours of my entertainment. I finally made him come in so the poor Squirrel can come out of the tree and Oso will have something to actually chase.
