FAQs
What other breeds are banned under the Dangerous Dogs Act?
As of 2026, five types are banned: Pit Bull Terrier, Japanese Tosa, Dogo Argentino, Fila Brasileiro, and American XL Bully. Note that identification is based on “type” (physical appearance and characteristics), not necessarily breed registration. The Dangerous Dogs Act 1991 (Amendment) Bill 2025 is currently under parliamentary review, aiming to require public consultation and data-driven evidence before any future breed additions.
