I traveled with a handler friend of mine I was at a show in Monroe, LA a couple of summers ago. While we were inside, showing the dogs (Chinese Shar Pei, TFT, and a couple of ringside pick up dogs), the breaker for the motor home a/c went out. Both of us had a couple of dogs that were not being shown that day or that had already finished being shown, so there were at least four dogs in the motor home, including a dog that was entered in the match that weekend. *If* we did not have the policy of checking hourly on the dogs, the situation could have been much worse--and if the weather had been a little hotter or if the motor home's second a/c unit had blown too OR if we had not had an extra fan blowing, I'm sure that we could have come back to dead dogs, as well. Accidents happen, even when you take precautions. Personally, if it had been me, I would not have gone to sleep until the dogs were taken care of, but if she took steps that she believed that she had taken precautions to keep the dogs safe and did not simply leave them in a dangerous situation, then I don't see how it could be considered negligence.
