Query: good resource if your dog is a resource guarder

If your dog is showing signs of resource guarding or possession aggression, this is the book for you. If you can catch it early before it becomes a serious issue, you might be able to address it yourself. However, if you are having a serious problem, please consult with a professional trainer and do not try to handle this on your own.
