If your going to go for a smaller breed of tracker, get a daushund. Short legs that you can keep up with and an unbelievable nose. They are fearless like the JR with a lot less energy to have to get rid of when not hunting. I understand that is the preferred breed by trackers up north.

Mine isn't a tracker, but I can attest to his nose. He can smell a dang lizard across my yard with the wind at his back. No idea why, but he hates a lizard worse than anything. A mole is a distant second.
