Owning a Rottweiler or a Pit Bull in Portugal

Last verified: October 2026.

Who this is for

  • You own, or plan to own, a Rottweiler, pit bull type, Staffordshire, or another listed breed in Portugal.
  • You are moving to Portugal with one of these dogs, or with a cross of them.
  • Your dog, of any breed, has bitten someone or killed another animal.

Not for you if: you are bringing an ordinary pet dog or cat. Read SIAC Microchip Registration for Pets instead.

Portugal bans no dog breed. Instead, seven listed breeds and their crosses are "potentially dangerous". Any dog that has bitten a person becomes "dangerous". Both groups follow special rules. You need a licence from your parish council (junta de freguesia), renewed every year. You need civil liability insurance with at least €50,000 of cover, and a keeper training course. In public, the dog must wear a muzzle and a lead of up to one metre. Unpapered listed dogs must be sterilised. Fines for a private person are €650 to €1,500.

Which dogs are covered

The law has two groups, and they work differently.

Potentially dangerous (potencialmente perigoso). This group depends on breed. The national veterinary authority, DGAV, lists seven breeds:

  • Cão de Fila Brasileiro (Brazilian Fila)
  • Dogo Argentino (Dogue Argentino)
  • Pit Bull Terrier
  • Rottweiler
  • American Staffordshire Terrier (Staffordshire Terrier Americano)
  • Staffordshire Bull Terrier
  • Tosa Inu

The group also covers first-generation crosses of these breeds, crosses between them, and crosses with other breeds that look similar to a listed breed. DGAV also says the dog known as the American Bully is potentially dangerous.

Dangerous (perigoso). This group depends on what the dog has done. Any breed can enter it. A dog becomes dangerous if it:

  • has bitten, attacked, or injured a person
  • has seriously injured or killed another animal outside its keeper's property
  • has been declared aggressive by its keeper to the junta
  • has been classed as a risk by a competent authority, because of aggressive behaviour or physical traits

So a Labrador that bites a delivery driver becomes a dangerous dog. Everything in this guide then applies to it.

The keeper (detentor) is the person responsible for watching the dog. The keeper must be at least 16 years old.

The licence from your junta

Every dog in Portugal must be registered in the national pet database, SIAC, and licensed each year by its junta. For most dogs, the first SIAC registration counts as the licence for a year. Dangerous and potentially dangerous dogs are the exception. They need a special licence from the junta where you live.

The law says you apply when the dog is between three and six months old. DGAV says the first licence must be issued within 30 days of the SIAC registration. The junta checks that you are fit to hold the licence.

Documents to bring

  • A statement of responsibility (termo de responsabilidade), on the model in the law
  • Your criminal record certificate (certificado de registo criminal). See Getting a Criminal Record Certificate in Portugal
  • Proof of civil liability insurance
  • Proof of sterilisation, where it is required
  • The dog's health booklet or pet passport, with this year's compulsory vaccination, including rabies
  • Proof that you passed the keeper training course

Some convictions count as a sign that you are not fit to keep these dogs. They include crimes under this law, crimes against animals, violent crimes, and drug, people, or arms trafficking.

Rules for the licence

  • It is valid for one year at most. You renew it every year.
  • Carry it whenever you take the dog out. Police and other authorities can ask for it.
  • It ends automatically after a final conviction for one of the listed crimes. You must hand it back at once.
  • The junta records the licence date in SIAC.

Keeper training

You must pass a training course for keepers of dangerous and potentially dangerous dogs. DGAV says the GNR and PSP run these courses. If you show you have enrolled, the junta can issue a provisional licence for three months.

Separately, you must have the dog trained in socialisation and obedience. The training must never aim at fighting or at making the dog more aggressive. Only a trainer with a professional title issued by DGAV may do it. Licensed trainers appear on DGAV's list. Training takes place at a training school, or on private land suitable for it. Ask to see the trainer's title before you pay.

Insurance: at least €50,000

You must hold civil liability insurance for the dog. The minimum terms are set by law:

  • Cover of at least €50,000 a year, however many incidents or injured people there are.
  • Area: mainland Portugal, the Azores, and Madeira.
  • Claims: events during the policy period are covered if claimed within one year after the policy ends.
  • Excess: allowed, but the insurer cannot use it against the injured person or their heirs.
  • Recourse: the insurer may recover what it paid from you for intentional acts, or acts while drunk or on drugs.

The law also lets insurers exclude some damage. Read your policy for these. Common permitted exclusions are:

  • injuries to your spouse or partner, parents, children, or anyone living with you or dependent on you, and to the person handling the dog
  • damage while hunting, which needs its own compulsory insurance
  • damage to other animals of the same species, meaning other dogs
  • fines, court costs, and bail
  • damage caused by breaking the legal rules on keeping pets, such as walking the dog without its muzzle

This is a specific policy for dangerous dogs. Check that it meets these terms. The liability cover in a home insurance policy may not. See Home Insurance in Portugal.

Where the dog lives

You must keep reinforced security where the dog lives. The housing must stop escapes and protect people, animals, and property. For dogs, the law requires:

  • Fencing at least 2 metres high, in strong material, between the dog's area and the street, public spaces, or neighbouring homes
  • Gaps of no more than 5 centimetres between railings, or between railings and gates or walls
  • Warning signs about the dog, easy to see and read, on the outside of the dog's housing and of your home

If you live in a flat, signs on the building and changes to shared areas are matters for the condominium. See Condominium Rules in Portugal.

In the street

These rules are the ones police check on sight:

  • The dog may never be out alone in the street, in public places, or in the shared parts of buildings. A keeper must always lead it.
  • The dog must wear a working muzzle that stops it eating and biting.
  • With the muzzle, it must be held on a short lead of up to one metre, fixed to a collar or harness. A long extending lead does not meet this rule.
  • The person walking the dog must be at least 16. If a younger person walks it, the adult keeper who allowed it is liable.
  • The dog may not enter zones that are signed as banned for these dogs.

There are only two exceptions to the muzzle and lead rule. They are dogs used in social therapy in a closed-off space, and dogs during hunting. See Hunting Season in Portugal.

The GNR, PSP, and municipal police must check dogs in public places systematically. They look at the microchip, the lead and muzzle, registration and licence, and whether a keeper is present.

Sterilisation and breeding

Who must be sterilised.

  • Dangerous dogs, and dogs that show aggressive behaviour, may not breed and must be sterilised.
  • Dogs of the seven listed breeds that are not in an officially recognised studbook, and crosses of these breeds, must be sterilised between four and six months of age.
  • DGAV can order any dog sterilised within 30 days if people or animals are at risk.

Within 15 days of the operation, hand in a vet's declaration at your junta. SIAC is then updated to show the dog is sterilised. If you prove you cannot pay for the operation, the câmara municipal must help.

Breeding and buying. These dogs may only be bred at commercial kennels with a permit from DGAV. Premises breeding without a permit are closed. A potentially dangerous dog may only be sold or given to its final keeper through such a kennel. At handover, the dog must be microchipped and in SIAC in the new keeper's name, with studbook proof and the junta licence. Selling or advertising dogs classed as dangerous is banned, except for authorised science.

Bringing one of these dogs to Portugal

The law sets a separate track for people who come with a listed breed:

  • Staying under four months: on arrival, show proof of registration in your home country and sign a statement of responsibility on DGAV's model.
  • Staying four months or more: take the dog to the municipal vet, who registers it. Unless it is in a recognised studbook, have it sterilised within 15 days. Send proof to the regional veterinary services within a further 15 days.
  • Unpapered listed dogs from another EU country or from outside the EU that stay more than four months must be sterilised.
  • Bringing a dog in to breed needs DGAV authorisation, requested seven days ahead. If DGAV does not answer in time, it is treated as approved.

For dogs from outside the EU, including the UK except Northern Ireland, DGAV issues the statement or a stay notice at the official points of entry. Dogs with recognised studbook papers are exempt, if you show written proof. All this is on top of the normal pet travel rules, covered in the SIAC guide linked above.

Fines and crimes

Breaking these rules is a serious economic offence. For a private person, the fine is €650 to €1,500. Offences include:

  • no licence, identification, or registration
  • no civil liability insurance
  • housing without the required security
  • being out without a keeper aged 16 or over, without a muzzle and short lead, or in a banned zone
  • breeding, or not sterilising, against the rules
  • no training, or training by a trainer without a DGAV title

Extra penalties can be added. They include losing the dog and a ban on keeping these dogs for up to ten years. They also include bans from fairs and shows, and closure or suspension of premises and permits for up to three years.

Some acts are crimes, not just offences:

  • Dog fights: promoting them, up to three years in prison or a fine; taking part with an animal, up to two years.
  • Setting a dog on someone: up to three years, or two to ten years if the injuries are serious.
  • Negligence: failing to watch or care for a dog so that it seriously injures a person, up to two years or a fine of up to 240 days.
  • Drunk or drugged: being out in public with one of these dogs with blood alcohol of 1.2 g/l or more, or under the influence of drugs. The penalty is up to one year or a fine of up to 360 days. Refusing the test is the crime of disobedience.

If a dog bites someone

The rules apply to any dog that injures a person:

  1. The authority must take the dog to an official holding centre, at the keeper's cost.
  2. Vets, police, courts, and health services that learn of the injury must tell the municipal vet straight away.
  3. Within eight days, the câmara tells the junta, which updates SIAC.
  4. The junta gives the keeper 15 days to hand in the full licence file, because the dog is now dangerous.

What happens next depends on the injury. If a medical report confirms serious injury, the municipal vet decides whether to put the dog down humanely, considering the circumstances. After a minor injury, the dog goes back to the keeper once the duties are met. The vet may require socialisation or obedience tests. A dog that is an immediate serious risk and that its keeper cannot control may be put down at once. There is no compensation.

If a neighbour's dog worries you

Report it to the câmara municipal and its municipal vet, or to the GNR or PSP. A written, dated complaint to the right body carries more weight than conversations at the gate. See Noise and Neighbours in Portugal for how complaints work.
