Many #dogs cannot stay calm when they see another dog/person/somethg in their environment. They *react* instead of observe. These reactions are grouped into 4 behavior categories: -> Fight (barking, lunging) -> Flight (avoiding, hiding) -> Freeze (cowering, shutting down) -> Fool Around (jumping, mouthing) Positive reinforcement methods (ex. the "Engage-Disengage Game") help dogs to become less anxious/fearful:http://www.clickertraining.com/reducing-leash-reactivity-the-engage-disengage-game
