Teddy is banned from agility

No, not an official banishment, but until his behavior improves, I have imposed a ban. He pulled the same stunt this past Thursday that he did the previous week - he barked, and Ranger ran off the course. I could see the struggle in Ranger's eyes - he wanted to obey me and come back to me when I called him, but he also wanted to see what Teddy wanted. Ultimately, Teddy won. Ranger ended up in a crate (one up high, no less, which he hates) and he faced the wall the entire time (his choice, not mine!) When it was our turn to run again, he did much better. Teddy barked and Ranger wanted to go to him, but my treats, and the threat of more time in the crate, won out and we finished.

There's no class this week, but next week, I may bring a friend, with strict instructions to have her remove Teddy from the room if he barks. I hate to leave Teddy at home, as socializing during class has helped him tremendously, but I'm paying money for Ranger to take the class, and if he runs off the course, I've wasted my money, and that drives me nuts. Hopefully my plan will work.
