UK dog law has changed more in the last two years than in the previous decade. The XL Bully ban is now fully enforced, microchip checks are tighter, breeder licensing has been overhauled, and councils are issuing record numbers of Public Spaces Protection Orders (PSPOs) restricting where dogs can go off-lead.
This 2026 guide explains every rule that applies to owning a dog in England, Scotland, Wales and Northern Ireland — what's new, what's enforced, and how to stay on the right side of the law.
Since 1 February 2024 it has been a criminal offence in England and Wales to own an XL Bully type dog without a valid Certificate of Exemption. Enforcement in 2026 is significantly stricter: police can seize unregistered dogs on sight, and DEFRA has confirmed no further amnesty windows will open.
Owners of exempt XL Bullies must:
Scotland introduced equivalent rules on 31 July 2024; Northern Ireland followed in July 2025. Penalties include unlimited fines, up to six months in prison, and seizure of the dog.
If you're unsure whether your dog meets the XL Bully type definition, see the [official DEFRA conformation guide](https://www.gov.uk/government/publications/xl-bully-dogs-officially-defined) — type is judged on physical conformation, not breed paperwork.
Microchipping has been compulsory for dogs over 8 weeks old since 2016, but 2026 brings stricter enforcement. From June 2024 cats are also required to be chipped, and councils are now cross-referencing chip databases with stray dog logs.
Key points for 2026:
If you've moved house, switched mobile number or rehomed a dog in 2026, log into your database within 21 days. This is the single most common compliance failure — and the easiest to fix.
Often forgotten, the Control of Dogs Order 1992 still applies in 2026. Every dog in a public place must wear a collar with the owner's name and address (postcode included) inscribed on it or on a tag. A microchip does not replace this requirement.
Exempt: working dogs (pack hounds, gun dogs while working, livestock dogs, dogs used by emergency services). For everyone else, a missing tag is a fine of up to £2,000 — though in practice councils typically issue warnings first.
Since 2014 the Dangerous Dogs Act has applied to all places, including private property. A dog that is "dangerously out of control" — even just causing reasonable apprehension that it might injure someone — can lead to prosecution.
In 2026 sentencing guidelines, the maximum penalties are:
This applies to any breed, not just banned types. Owners of breeds with a guarding instinct should be especially aware — see our guide to the [best guard dogs for families](/blog/best-guard-dogs-for-families) for breeds that combine protective traits with stable temperament.
Public Spaces Protection Orders are now the single biggest source of on-the-ground enforcement. As of early 2026, over 80% of UK local authorities have at least one dog-related PSPO. Common provisions:
Check your local council website before walking in unfamiliar areas. PSPO breaches are fixed penalty notices of £100, rising to £1,000 on conviction.
The standard fixed penalty for failing to pick up dog mess has risen to £100–£150 in 2026, with some councils (Westminster, Birmingham, Glasgow) charging the £150 maximum. Non-payment escalates to court and a fine of up to £1,000.
Since 2020 (England), 2021 (Wales) and 2024 (Scotland), third-party puppy and kitten sales are banned. In 2026 enforcement has shifted to online listings — Pets4Homes, Gumtree and Facebook Marketplace now require licence numbers to be displayed.

Since Brexit, UK pet passports issued in Great Britain are no longer valid for EU travel. In 2026 you need:
AHCs cost £150–£300 per trip — a major reason multi-trip pet owners are switching to the new GB Pet Travel Document, which DEFRA confirmed will launch in late 2026 for frequent travellers.
The Animal Welfare Act 2006 (and the Animal Welfare (Sentencing) Act 2021, which raised maximum sentences to 5 years) sets out five welfare needs every owner must provide:
1. A suitable environment 2. A suitable diet 3. The ability to exhibit normal behaviour 4. Appropriate company (or solitude) 5. Protection from pain, suffering, injury and disease
Failing to meet these — including leaving a dog alone for excessive periods, feeding inappropriately, or denying vet care — can lead to prosecution even where no obvious cruelty has occurred. RSPCA inspectors filed over 10,000 dog welfare cases in 2025.
There is no general legal requirement to insure your dog in the UK — but:
In 2026, lifetime cover from a reputable UK insurer typically costs £20–£60/month depending on breed and age. See our up-to-date comparison in [Best Pet Insurance for Dogs UK 2025/26](/blog/best-pet-insurance-uk).
Getting these basics right keeps you out of court — and out of the £500–£2,000 fine bracket that thousands of UK owners walk into each year purely through admin slip-ups.
Only without a Certificate of Exemption. Owning an unregistered XL Bully in England, Wales, Scotland or Northern Ireland is a criminal offence punishable by unlimited fines and up to six months in prison. Exempt dogs must be muzzled and leashed in public, neutered, insured, and kept in a secure environment.
Failing to chip your dog by 8 weeks old, or failing to keep contact details up to date on a DEFRA-approved database, can lead to a £500 fine if you don't comply within 21 days of being served notice.
Yes. The Control of Dogs Order 1992 requires every dog in a public place to wear a collar with the owner's name and address (including postcode). A microchip does not replace this requirement. Maximum fine is £2,000.
Most councils issue a fixed penalty of £100–£150 in 2026, rising to a £1,000 court fine if unpaid. Some local authorities also fine owners £100 simply for not carrying poo bags.
Only for exempt XL Bullies, who must hold valid third-party liability insurance. For all other dogs insurance is optional but strongly recommended, with lifetime cover typically £20–£60/month.
An Animal Health Certificate from an Official Veterinarian (issued within 10 days of travel), an up-to-date rabies vaccination, and a tapeworm treatment 24–120 hours before returning to GB. AHCs cost £150–£300 per trip.
