Disclaimer: I am not a solicitor. This article provides general information for UK dog owners and is not legal advice. Rules and official guidance can change. Always check the latest guidance for England and Wales, Scotland or Northern Ireland and seek qualified legal advice about an individual case.
The XL Bully restrictions remain fully in force across the UK in 2026. An XL Bully-type dog can only be legally kept with a valid Certificate of Exemption, and exempted dogs must continue to meet strict conditions throughout their lives.
The law is important, but responsible ownership involves more than completing paperwork. Owners must also use suitable equipment, understand their dog’s behaviour, prevent avoidable incidents and keep the dog safely under control at home and in public.
What does the XL Bully ban mean in 2026?
It is now illegal to own or possess an XL Bully-type dog without a valid Certificate of Exemption.
It is also illegal to:
sell an XL Bully
give one away
transfer ownership
breed or breed from one
abandon one
allow one to stray
have one in public without a lead and muzzle
The original owner-led exemption application periods have closed.
In England and Wales, owners who believe they have an XL Bully but do not have a Certificate of Exemption are instructed to contact their local police force. In Scotland, new exemptions can only be granted following court authorisation. In Northern Ireland, an owner without an exemption should contact the dog-control section of their local council.
Is the XL Bully law the same throughout the UK?
The main restrictions are very similar, but the rules are administered differently depending on where the dog lives.
England and Wales
The Certificate of Exemption is administered through the Index of Exempted Dogs and the Department for Environment, Food and Rural Affairs.
An exempted XL Bully must be kept on a lead and muzzled in public, securely contained at home, microchipped and permanently neutered.
Scotland
Scotland introduced its own XL Bully legislation and exemption process.
The dog must continue to comply with Scotland’s exemption conditions, including remaining on a lead and muzzled in public and being kept securely so it cannot escape
.
Northern Ireland
In Northern Ireland, local councils are responsible for administering and enforcing the exemption scheme.
In addition to having a valid exemption, an XL Bully must continue to hold a valid Northern Ireland dog licence. The licence must be renewed every 12 months for the exemption to remain valid.
Owners should always follow the guidance for the part of the UK where the dog is registered and normally kept.
What must an exempted XL Bully owner do?
The exemption conditions must be followed for the rest of the dog’s life.
An exempted XL Bully must generally be:
permanently neutered
microchipped
registered with the correct keeper details
kept in secure conditions so it cannot escape
kept on a lead in public
muzzled in public
handled in public by someone aged 16 or over
kept at the address registered to the certificate holder
The dog may normally stay at a different address for no more than 30 days during any 12-month period.
Owners must also report important changes, including:
a permanent change of address
a change to relevant contact details
the death of the dog
the permanent export of the dog
When requested by the police or an authorised council officer, the owner may have to provide access to the dog so its microchip can be checked and produce the Certificate of Exemption within five days.
Failing to follow the conditions can invalidate the exemption. The dog may be seized and the owner could face prosecution.
Do XL Bully owners still need third-party liability insurance?
From 1 July 2026, third-party public liability insurance is no longer a legal exemption requirement for banned dog types, including XL Bullies.
The requirement was removed because the remaining provider stopped offering new policies and renewals and no suitable alternative policy was available.
This does not remove any of the other exemption conditions. Exempted dogs must still be:
on a lead in public
muzzled in public
microchipped
neutered
kept securely
handled in accordance with the exemption rules
Owners also remain responsible for any injury or damage caused by their dogs.
What is changing for XL Bully owners in November 2026?
A further safety condition comes into force on 1 November 2026.
From that date, a child under 12 must not be left in close contact with an XL Bully or another prohibited-type dog in a private place without adult supervision.
Private places include:
the family home
another person’s home
a private garden
other areas not open to the general public
An adult aged 16 or over must be present.
This becomes a condition of the Certificate of Exemption. Failure to comply could lead to enforcement action, prosecution or seizure of the dog.
Young children should be actively supervised around every dog, regardless of its breed, size, temperament or legal status.
Is an XL Bully identified by its breed registration?
The XL Bully restriction is based on type and physical appearance, not simply the breed name written on paperwork.
A dog may be assessed against the official physical conformation standard even when it is:
described as another breed
registered as a crossbreed
sold under a different name
not registered with a recognised breed organisation
descended from dogs described as another bully type
The assessment looks at the dog’s overall physical characteristics, including its height, build, head, body, legs, feet, tail and coat.
The same underlying conformation standard is used in England and Wales, Scotland and Northern Ireland.
A DNA test, veterinary record or breeder’s description does not automatically decide whether a dog is legally considered an XL Bully type.
Can an exempted XL Bully be rehomed?
No. A Certificate of Exemption does not allow an owner to sell, gift or rehome the dog.
It remains illegal to:
sell the dog
advertise the dog for sale
give the dog away
transfer ownership to a friend or relative
transfer the dog to a rescue organisation
breed from the dog
Rescue organisations are also prohibited from rehoming XL Bully-type dogs.
Owners experiencing serious illness, housing difficulties or another crisis should seek legal and official advice before making any arrangements involving their dog. Informally handing the dog to someone else could break the law.
What does “dangerously out of control” mean?
The law concerning dangerously out-of-control dogs is not limited to XL Bullies or banned types.
In England and Wales, a dog may be considered dangerously out of control if it:
injures someone
makes someone reasonably worried that it might injure them
The law can apply in a public place, another person’s property and the owner’s own home or garden.
A court may also consider a dog dangerously out of control if it attacks another animal or if someone reasonably fears being injured while trying to stop an attack on their animal.
Scotland has additional dog-control procedures, including Dog Control Notices for dogs that are not being kept under effective and consistent control and whose behaviour reasonably causes alarm or fear.
Northern Ireland has separate dog-control legislation. It is an offence there to allow a dog to attack or seriously injure a person or livestock, or to behave in a way that makes someone fear it may attack.
The exact legal test depends on where the incident happens and the individual circumstances.
Can barking or lunging be treated seriously?
Barking on its own does not automatically mean that a dog is dangerously out of control.
However, the overall situation matters.
Behaviour may be treated more seriously when a dog:
repeatedly lunges towards someone
drags its handler forwards
cannot be physically restrained
attempts to bite
charges at a person or dog
escapes from a home or garden
behaves in a way that creates a reasonable fear of injury
A dog does not always have to bite before authorities become involved.
For XL Bully owners, prevention is especially important because breaking exemption conditions can place the dog’s legal status at risk.
Does a friendly XL Bully still need a lead and muzzle?
Yes.
An exempted XL Bully must remain on a lead and muzzled in public even if the dog:
has never bitten
is friendly with people
is calm around other dogs
has passed training assessments
has no history of complaints
has lived peacefully with its family for years
The conditions apply because of the dog’s legal classification, not because of its individual behaviour.
Training does not remove the legal requirement, and there is no exception for quiet parks, empty roads or familiar walking routes.
What type of muzzle should an XL Bully wear?
A correctly fitted basket muzzle is generally the most suitable option for walking.
The muzzle should give the dog enough room to:
open its mouth
pant properly
breathe without restriction
drink
take small training rewards
Panting is essential because it helps dogs regulate their body temperature.
The muzzle should not:
press into the dog’s eyes
rub the nose
restrict normal mouth movement
prevent the dog from panting
be loose enough for the dog to remove
Tight fabric or grooming muzzles that hold the mouth closed are not suitable for ordinary walks or prolonged wear.
How should you muzzle-train an XL Bully?
Muzzle training should be gradual, positive and reward based.
Do not push the muzzle onto the dog’s face and immediately fasten it. This can create fear and make future handling more difficult.
Step 1: Let the dog investigate
Place the muzzle nearby and reward the dog for calmly looking at or approaching it.
Step 2: Encourage voluntary nose placement
Hold the muzzle still and place a treat inside. Allow the dog to put its own nose into it.
The dog should always be free to move its head away during the early stages.
Step 3: Build duration
Gradually reward the dog for keeping its nose in the muzzle for slightly longer periods.
Step 4: Introduce the straps
Let the dog become familiar with the movement and sound of the buckle before fastening it.
Step 5: Fasten it briefly
Fasten the muzzle for only a second or two, reward the dog and remove it.
Step 6: Add movement
Practise a few steps indoors or in the garden before progressing to short, quiet walks.
Keep sessions short and return to an easier stage if the dog paws at the muzzle, freezes, tries to escape or refuses food.
For an exempted XL Bully, muzzle training must be practised in a way that does not breach the law. The dog still needs to be legally muzzled whenever it is in public.
Will wearing a muzzle stop reactivity?
No. A muzzle can reduce the risk of a bite, but it does not change how a dog feels.
A frightened, frustrated or overwhelmed dog may still:
bark
lunge
charge forwards
knock someone over
redirect onto the lead
become increasingly distressed
Even when the dog is muzzled, owners should avoid placing it too close to situations that make it fearful or reactive.
Dogs Trust advises that a muzzle does not change a dog’s emotional response to a trigger. Repeated exposure to frightening situations can make the behaviour worse rather than helping the dog “get used to it.”
A muzzle is a safety tool. It is not a complete behaviour programme.
Why can a normally calm dog react unexpectedly?
Dogs do not react without a reason, although the reason may not always be obvious to the owner.
Common factors include:
fear
frustration
excitement
pain
illness
lack of sleep
unfamiliar surroundings
being approached too closely
repeated stressful encounters
feeling trapped on a short lead
rough or unexpected handling
an off-lead dog rushing towards them
A dog that appears calm at home may behave differently in a crowded park, narrow pathway or unfamiliar veterinary waiting room.
Stress can build across several events. A dog may cope with the first trigger but react strongly after several difficult encounters without enough time to recover.
Can pain cause sudden aggression or reactivity?
Yes. Pain or illness can change a dog’s tolerance and behaviour.
A dog experiencing discomfort may:
avoid being touched
become restless
struggle to settle
growl when approached
react when its collar or harness is handled
become less tolerant of children or other dogs
refuse activities it previously enjoyed
snap when getting up, lying down or being moved
A sudden behavioural change should always be discussed with a vet.
The RSPCA advises owners to seek veterinary advice when behaviour changes because illness, injury or pain can contribute to defensive or aggressive behaviour.
How can owners keep an XL Bully safer and calmer in public?
Calm public behaviour is built through a combination of legal compliance, suitable equipment, training and sensible management.
Follow the law every time
Before leaving home, check:
the muzzle is correctly fitted
the lead is secure
the collar or harness is undamaged
the person holding the lead is aged 16 or over
the handler can physically control the dog
Do not remove the muzzle or lead simply because an area appears empty.
Create distance early
Do not wait until the dog is already barking or lunging.
Cross the road, turn around or move behind a barrier as soon as you notice a difficult situation approaching.
Creating distance is not a failure. It is responsible management.
Avoid forced greetings
Your dog does not need to meet every person or dog it passes.
Lead-to-lead greetings can create pressure because the dogs cannot move freely or leave naturally.
It is acceptable to say:
“Please call your dog back. Mine needs space.”
Reward calm attention
Useful skills include:
responding to the dog’s name
looking back at the handler
walking on a loose lead
turning away on cue
leaving food or objects
settling calmly
waiting at doors
remaining beside the handler while others pass
Reward the behaviour you want to see instead of waiting for the dog to make a mistake.
Choose quieter walking times
A short, successful walk can be more beneficial than a long walk filled with repeated triggers.
Consider:
quieter routes
wider paths
less crowded times
areas with clear visibility
routes with safe places to turn around
Plan for off-lead dogs
An off-lead dog rushing towards a muzzled dog can create a difficult and unfair situation.
Where possible:
move away
use a parked vehicle, gate or hedge as a barrier
ask the other owner to recall their dog
keep your own lead controlled without pulling the dog into a tight confrontation
leave the area rather than allowing a forced greeting
Which training skills matter most?
Owners do not need dozens of complicated commands. A small number of reliable skills can make everyday situations much safer.
Name response
The dog immediately looks towards the handler when its name is called.
Emergency turn
A cue that means the dog turns around and moves away with the handler.
Loose-lead walking
The dog learns that staying near the handler is rewarding.
Leave it
The dog moves away from food, objects, animals or another distraction.
Settle
The dog relaxes on a bed or mat and remains there until released.
Doorway control
The dog waits rather than rushing through an open door or gate.
Practise these skills in quiet places before expecting the dog to perform them around strong distractions.
Why management is just as important as training
Training teaches a dog what to do. Management prevents the dog from repeatedly practising unsafe behaviour while that training develops.
Good management may include:
secure fencing
locked gates
warning visitors before they enter
using baby gates inside the home
separating the dog during deliveries
preventing access to an open front door
using two secure points of attachment when appropriate
keeping children away from the dog’s food and sleeping area
avoiding crowded events
Management is not giving up on training. It is part of responsible ownership.
How should XL Bully owners manage visitors at home?
Incidents do not only happen on walks.
Before opening the door:
place the dog behind a secure internal barrier
make sure external gates are closed
prevent the dog from rushing into the hallway
tell visitors not to approach or touch the dog without permission
supervise all interactions
give the dog a quiet place where it will not be disturbed
Delivery workers, tradespeople and unfamiliar visitors should not be expected to judge whether a dog is friendly.
Owners should create a safe system before the door opens.
When should you contact a trainer or behaviourist?
Seek professional help when a dog:
repeatedly lunges at people or animals
has snapped or attempted to bite
has already bitten
redirects towards its handler
guards food, toys, furniture or doorways
takes a long time to recover after a trigger
becomes difficult to restrain
shows a sudden change in behaviour
appears frightened during ordinary walks
cannot safely cope with visitors
Start with a veterinary examination to rule out pain or illness.
For serious fear, aggression or a bite history, look for a suitably qualified clinical animal behaviourist. The Animal Behaviour and Training Council maintains a register of practitioners working to recognised professional standards.
Can supplements calm an aggressive or reactive dog?
No supplement can:
make an XL Bully legally compliant
replace a lead or muzzle
guarantee that a dog will not bite
treat aggression on its own
replace veterinary care
replace professional behaviour support
Nutrition can support general health, muscle condition, mobility and recovery, but owners must not rely on a supplement to control dangerous or unpredictable behaviour.
When a dog’s behaviour suddenly changes, pain and illness should be ruled out first.
Complementary feeds may be used as part of an appropriate nutrition programme, but they should never be presented as an alternative to legal compliance, training, management or veterinary advice.
A practical 30-day safety and training plan
This plan does not replace the exemption conditions or individual professional advice.
Week 1: Check safety and health
Check the dog’s exemption details.
Confirm the microchip information is correct.
Inspect the muzzle, collar, harness and lead.
Check fences, gates and doors.
Arrange a veterinary examination if behaviour has changed.
Begin short, positive muzzle exercises at home.
Week 2: Build foundation skills
Practise name response.
Reward loose-lead walking.
Introduce an emergency turn cue.
Practise waiting at doors.
Teach a calm settle on a mat.
Keep training sessions short and successful.
Week 3: Practise at a safe distance
Work around mild distractions.
Reward the dog for looking back at the handler.
Move away before the dog becomes overwhelmed.
Avoid forced greetings.
Choose quiet, open walking locations.
Record the dog’s common triggers.
Week 4: Review and strengthen
Identify which situations remain difficult.
Increase distance from strong triggers.
Continue muzzle practice.
Strengthen home-management routines.
Arrange professional help if safety remains a concern.
Continue practising rather than assuming the problem is solved.
Frequently asked questions about the XL Bully law
Can an exempted XL Bully be off lead in public?
No. An exempted XL Bully must be kept on a lead and muzzled in public.
Can the muzzle come off when nobody else is nearby?
No. The public-muzzling condition is not limited to crowded places or situations where other people can be seen.
Does an XL Bully have to be muzzled in its own home?
The general exemption condition requires the dog to be muzzled in public. It does not normally require routine muzzling inside the owner’s private home.
However, a court order or another individual restriction may impose additional conditions.
Owners must still manage the dog safely around visitors, children and other animals.
Is a muzzle only for aggressive dogs?
No.
Dogs may wear muzzles because of:
legal requirements
scavenging
veterinary handling
fear
previous incidents
chasing behaviour
a professional safety plan
A muzzle should not be treated as a sign that either the dog or owner is bad.
Does the Certificate of Exemption last for life?
The certificate can remain valid for the dog’s life, provided the owner continues to follow all of its conditions.
Breaching the conditions could invalidate the exemption.
What happens if an owner moves home?
The relevant authority must be informed of a permanent address change.
England and Wales owners should update Defra. Scottish owners should contact the Scottish Government’s XL Bully team. Northern Irish owners should notify their local council.
What should an owner do if neutering evidence was never submitted?
The owner should contact the relevant police force, government exemption team or local council immediately and obtain legal advice.
Continuing to ignore a missed condition could place the dog’s exemption status at risk.
Are XL Bullies automatically aggressive?
No individual dog’s behaviour can be predicted solely from a label.
However, the exemption restrictions apply regardless of the individual dog’s temperament or history. Owners must follow them even when their dog has always behaved calmly.
The most important message for XL Bully owners
Responsible ownership is not about insisting that an incident could never happen.
It means:
understanding the law
following every exemption condition
using suitable and humane equipment
securing the home and garden
recognising stress before it escalates
creating distance from difficult situations
seeking veterinary and behavioural help early
A lead and correctly fitted basket muzzle do not make a dog bad.
Used properly, they protect the dog, the owner and the wider public while allowing the dog to continue enjoying safe, structured walks.
If a dog presents an immediate danger, call 999. For a non-emergency concern about a dangerously out-of-control dog, contact the police on 101 or the relevant local council dog-control service.
