Rhodesian Ridgeback.

Definitely certain traits are fully built-in various dogs. Ridgebacks are primarily "bay dogs" - that is for hunting they corral prey so that human hunters can come finish them off.

My dog definitely does that, sometimes to comical effect. One time I saw her standing in backyard with her foot on something...looking pleadingly towards the house, almost as if she were stuck. I went and saw she had trapped a frog. Didn't kill it or bite it, just held it there waiting for me (no frogs were shot that day).
