I ended up taking the dogs to the far end of the dead deer trail. I had to leash up Tod to get him in the car, but I think he enjoyed himself--until he went down the bank to get in the water and had a hard time making the jump to start back up the hill. It's hell getting old!
Izzy made it back up without any problems.
Once Tod finally made it back up, of course Izzy was in his face.
