Dog bite laws in the UK

If you’ve been bitten or injured by a dog, understanding dog bite law in the UK can feel confusing at first.

That’s because there isn’t just one law that applies. Instead, there are two main legal routes, and they do very different things:

• The Animals Act 1971 covers your right to claim compensation
• The Dangerous Dogs Act 1991 deals with criminal offences and penalties

This guide explains dog bite laws in the UK in clear, simple terms so you know where you stand and what your options are.

The Animals Act 1971 – the civil law for dog bite claims

When people ask what the law is on dog bites in the UK, this is the most important one for compensation.

What is the Animals Act 1971?

The Animals Act 1971 is the main law that allows you to claim compensation if a dog injures you.

It places legal responsibility on the dog’s owner or keeper. In simple terms, they can be held responsible for harm caused by their dog.

What does “strict liability” mean?

Under section 2(2) of the Act, the law applies strict liability.

This means:

• You don’t need to prove the owner was careless
• You don’t need to show they knew the dog was dangerous
• You only need to show that the legal conditions are met

So even if the owner says the dog has never behaved like this before, that alone won’t prevent a claim.

The three conditions explained in plain English

To succeed under section 2(2), three things usually need to apply:

• The injury was likely to happen in this type of situation

Dogs can react suddenly if they feel threatened, startled or protective.

• The risk of injury came from the dog’s normal behaviour in certain circumstances

For example, guarding territory, reacting to fear or chasing.

• The owner knew about that risk

Not that the dog had bitten before, but that dogs can behave this way in those situations.

This is why many claims succeed even where there was no previous history of aggression.

A key case, Mirvahedy v Henley [2003], confirmed that strict liability can still apply even when an animal is behaving in a way that’s normal for its species in certain situations.

Are there any defences?

Yes, but they’re limited. The owner may try to argue:

• You were trespassing
• You accepted the risk
• The incident was entirely your fault

These arguments depend on the facts. In practice, they don’t often prevent a claim entirely.

How is compensation calculated?

Compensation is based on:

• The severity of your injuries
• Your recovery time
• Any financial losses, such as lost earnings or treatment costs

Courts often refer to the Judicial College Guidelines, which provide compensation ranges for different types of injury.

The Dangerous Dogs Act 1991 – the criminal law

While the Animals Act focuses on compensation, the Dangerous Dogs Act deals with criminal responsibility.

What does the Dangerous Dogs Act do?

The Dangerous Dogs Act 1991 makes it a criminal offence for a dog to be dangerously out of control.

This applies if a dog:

• Injures someone, or
• Makes someone reasonably fear injury

This can happen in public or private places.

What penalties can owners face?

If convicted, an owner may face:

• An unlimited fine
• Up to 14 years in prison if the attack causes serious injury or death
• The dog being destroyed
• A ban on owning dogs in the future

The XL Bully ban

A major recent development is the ban on XL Bully type dogs.

Since February 2024:

• XL Bullies are classed as a prohibited type
• Owning one without an exemption certificate is a criminal offence
• Strict conditions apply even if exempt

This has made enforcement stricter, and courts now treat attacks involving these dogs very seriously.

Can you claim compensation under this law?

No. The Dangerous Dogs Act doesn’t provide a route to compensation.

Your right to claim comes from the Animals Act 1971, even if the police are also involved.

If you’re unsure what steps to take after an incident, understanding how to report a dangerous dog can also be important.

The difference between the Animals Act 1971 and the Dangerous Dogs Act 1991

If you’re trying to understand dog bite law in the UK, it helps to compare the two:

Both laws can apply to the same incident. For example, the police may prosecute the owner, while you pursue a compensation claim at the same time.

Other relevant laws

There are a few additional rules that form part of dog bite law in the UK, although they are less central to compensation claims:

• Environmental Protection Act 1990

Local councils can deal with stray dogs and certain nuisance issues

• Road Traffic Act 1988
