Looks like it was a bad match of dog and owner. He had a dog that is a working dog and needs something to do to occupy its time. Absentee ownership is not good for any dog, IMO; it’s particularly bad for Border Collie-type dogs. She’ll probably be a great dog for someone else.
Yes, and wasn’t the car owner a great person by failing to warn the rescue society of this dog’s penchant for chewing! Idiot!
