Axl is a sweet boy at home but has been going after people's shoes. I've experienced this behavior issues before, it's called fear aggression.
Fear aggression is characterized by rapid nips or bites because a fearful dog is motivated to bite and then run away. Sometimes the aggression doesn't begin with clear threats. A fearful dog might not show her teeth or growl to warn the victim off.
