Unfortunately she does not seem to enjoy the company of other dogs which means that the shelter is looking for someone with no other dogs to adopt her. Fortunately, she is in a foster home and not in the kennels. I hate to see the older ones in the shelter ... and more so for those who don't like other dogs. It's a great environment to culture a negative behaviour that has been budding.
