Jack has calmed down quite a bit. For a while, there, they'd be waiting at the clinic door with a sedative for him. Poor dufuss.
You know.... I hear that cattle dogs are typically pretty high-drive high-energy high-anxiety kind of dogs, and I've seen them in frisbee competitions and such, and yet, my only experience with them was a friend's, and hers was the slowest, dopiest, most inattentive dog. She was trying to show him in obedience and he just dragged himself through it. I wonder if he didn't have a thyroid problem or anemia or other illness that made him so down.
