I felt bad for him. I wish I could let him off his leash so he could chase after them, although then it would take me forever to get him back inside. It was rather entertaining to watch him hunt this squirrel down. His tail was wagging and he was fully concentrated on the location of the critter. I'd love to let him loose in the wild and see what he could catch. You can just tell these guys are meant to survive on their own.
