If you holler 'Cat' or 'Squirrel,' Rowdy is up for the chase. I believe 'chase' is all he does, because when he catches up to it, it becomes a standoff, or it is up a tree and he can no longer reach it.
So the other day, there was a cat roaming around in the street in front of my house. So I got Rowdy's attention by hollering 'Cat' and he came running up to the door. Then I said, "Get the cat, get the cat!" and he tore off after it at full speed. The cat ran away for a short distance and then turned, arched it's back and stood it's ground. Rowdy stopped within 3 feet of it, stood there for a few seconds sizing up the situation and then backed away. I laughed and called him a chicken dog and called him back to the house. The little chicken dog came running back to the house all proud and happy from his chase.
