A friend of mine, had his truck, and trailer parked while he ran an errand on foot (not sure how long he was gone, but it wasn't long). He had his horse on the trailer, and his dog in the back seat. Came back, all gone. Impounded, for the animals safety and well being. Reason given, too cold for them (55 degrees yesterday at the time of the incident). Neither the dog nor the horse would accept water when they arrived at the vet office. He has his rig and animals back. No charges were filed, and he hasn't decided yet what his level of concern is.
