One night at training I didn't have enough crates. Dottie was left uncrated while I worked Pie. The windows were cracked about 6 inches. Apparently that is enough room for Dottie to weasel her way out and join us on the field! I saw her coming and shouted her name in exasperation, but no command because I knew it wouldn't be a problem. When Dottie showed up and started barking, Pie backed off in confusion, but then came back in. Here they are both tugging on the sleeve. They both got a bite at the same time- wish I had a picture of that!
Dottie's normal turn.
Pie anticipating her bite.
