Breeding out DA

[Dekka]

Take earth dogs (the true terriers) they need to go down a hole and have enough 'fight' and prey drive to stay down there and engage the prey.

I have been hunting, it takes a very drivey dog to stay alone in the dark in cramped quarters and face quarry that is of similar size in its own den. You need a dog willing to take damage to do it. This ends up breeding dogs who not only don't back down to confrontation but tend to escalate when presented with confrontation and or pain.
