Understanding a dog's body language and behavior signals can help reduce the risk of dog bites. A study found that both children and adults had difficulty correctly interpreting signals like snarling and growling. Through a training program that explained different behaviors, participants improved their ability to judge when a dog was distressed or showing high-risk signals. The training effects lasted for over a year. Key signals that a dog may bite include raised fur, a rigid stiff body, and a slow tail wag while remaining still - which indicates the dog feels uncomfortable or on edge in its surroundings. The study demonstrated training people to recognize dog signals can help interactions stay safe.
