According to Chapter 822, how is a dog defined as dangerous?

A dog is defined as dangerous under Chapter 822 if it attacks a person within an enclosed area. This definition emphasizes the behavior of the dog in relation to human safety and indicates that the dog's actions pose a direct threat to individuals. The focus is on the act of attacking, rather than merely exhibiting aggressive behaviors such as growling, which may not necessarily result in harm. Additionally, the law does not classify dogs as dangerous based solely on breed, as many breeds can be friendly and well-behaved. The legal definition is primarily concerned with actual aggression and the consequences that arise from an attack, making this specific aspect critical in determining a dangerous dog.
