Under what circumstance is a dog defined as dangerous according to Chapter 822?

A dog is defined as dangerous according to Chapter 822 primarily based on its behavior in relation to attacking or posing a threat to humans. The specific criterion that classifies a dog as dangerous involves an actual attack on a person, emphasizing the seriousness of the behavior. This classification is crucial for public safety, as it distinguishes between aggressive behavior that may not pose an imminent threat and behavior that has resulted in harm.

The other circumstances listed—such as excessive barking, growling at strangers, or escaping the yard—can indicate a dog's potential for aggression or behavioral issues, but they do not meet the legal threshold of being classified as dangerous. These behaviors might warrant attention or intervention, but they lack the definitive nature of an actual attack, which is necessary for the legal designation of a dog as dangerous under Chapter 822. The focus on an attack demonstrates the importance of clear, actionable criteria in animal control law, aimed at ensuring public safety and responsible pet ownership.
