I am feeling much better. My cough is almost gone, and I am back into my nightly training session with mom. That's really good, because I was starting to wonder if that part of my life was all over with.
We worked on heel position (yay!), formal obedience come (yay!), long sit and down stays (yay!), left and right (yay!), 2-on 2-off (yay, the board is back in the hallway for the winter), go to my tunnel (double yay!), and fetch (notso yay). Mom is just not making sense with that dumbbell thing. She says she will reconsider her criteria and we'll try again tonight. yay!
