What is included in the definition of a 'secure enclosure' for a dangerous dog?

A 'secure enclosure' for a dangerous dog is defined as a structure that is locked and marked to ensure it can safely contain the animal and prevent any potential escape. This requirement emphasizes not only physical containment but also the importance of clearly identifying the enclosure to both the public and any handlers, which serves to warn others of the potential danger. Locking the enclosure adds a layer of safety by ensuring that the enclosure is not easily accessed by individuals who may inadvertently or intentionally allow the dog to escape.

Other options do not meet the necessary criteria of a secure enclosure. An open yard with a fence may not be secure if the fence is not high enough or if there are gaps, leaving opportunities for the dog to escape. A space without any barriers provides no containment and presents a risk of the dog causing harm. Lastly, any area that the dog prefers does not necessarily take into account the safety features needed to securely contain a dangerous dog; preference does not equate to security. Therefore, the definition focusing on a locked and marked structure is the essential criterion for ensuring safety and control over a dangerous dog.
