In the UK, it is against the law to own, breed, sell, abandon, or give away certain types of dogs under the Dangerous Dogs Act. The following breeds are banned in the UK:

• Pit Bull Terrier
• Japanese Tosa
• Dogo Argentino
• Fila Brasileiro

It is important to note that whether a dog is a banned type depends on what it looks like, rather than its breed or name. For example, if a dog matches many of the characteristics of a Pit Bull Terrier, it may be considered a banned type. Additionally, the American XL Bully is not currently a banned breed in the UK, but there have been calls to add it to the list due to recent attacks.
