The four breeds covered by the act are:
1. Pit Bull Terrier
2. Japanese Tosa
3. Dogo Argentino
4. Fila Brasileiro
It's important to note that the Act focuses on characteristics, not simply breed. Any dog that exhibits certain traits, regardless of breed, can be subject to the Act's provisions. This includes:
* Being bred for fighting
* Being used for fighting
* Having a history of aggression
It's also important to understand that the act doesn't mean that all dogs of these four breeds are dangerous. It is the responsibility of the owner to ensure their dog is well-trained, socialized, and cared for to prevent any potential aggression.
