The Dangerous Dogs Act 1991 is one of the most significant pieces of legislation affecting dog owners in the UK. Whether you’re a new dog owner or long-established, all dog owners should be aware of its implications—whether you own a gentle teacup Chihuahua or a large guarding breed.
The Dangerous Dogs Act 1991 was introduced in response to a series of dog attack incidents in the late 1980s and early 1990s. The law has two principal sections that affect dog owners:
The Dangerous Dogs Act 1991 prohibits four types of dogs:
However, the Act also applies to any dog of any breed that poses a risk to people, which many dog owners may not fully appreciate. It is not about the breed alone, but about the individual dog's behaviour and appearance.
In May 2014, significant amendments to the Dangerous Dogs Act came into force. Previously, Section 3 only applied to public places. The 2014 amendments extended the Act's provisions to include private property, meaning dogs can now be prosecuted for attacking someone in a private home or garden, not just in public. This change has significant implications for all dog owners:
The penalties for offences under the Dangerous Dogs Act are severe:
A dog is considered dangerously out of control if it injures someone or if a person has reasonable grounds to be afraid the dog will injure them. This applies to all breeds, not just prohibited types. Even a small dog barking aggressively at a postman through a garden gate could potentially be considered a concern under the Act, highlighting why responsible ownership is essential for all dog owners.
All dog owners must ensure their dogs are well-socialised, properly trained, and managed responsibly. This includes ensuring your dog cannot escape from your property, is kept under control in public, and does not pose a threat to others. Dogs should be properly identified by microchip and kept up to date with vet care. Responsible ownership also means addressing any aggressive behaviour early with professional behavioural support.
Some Pit Bull Terrier-type dogs can be placed on the Index of Exempted Dogs (IED) if assessed as safe. These dogs must be neutered, microchipped, tattooed, insured, and kept on a lead and muzzled in public at all times. Owners must also meet other strict conditions. This allows some dogs to live out their lives rather than face destruction.
