Can I keep a dangerous-breed dog?
Conditional: you can, but with a licence, insurance and strict rules. Portugal does have a list of potentially dangerous breeds (Ordinance 422/2004): Brazilian Mastiff (Fila), Dogo Argentino, Pit Bull Terrier, Rottweiler, American Staffordshire Terrier, Staffordshire Bull Terrier and Tosa Inu (and first-generation crosses). In public, these dogs need a leash up to 1 metre and a muzzle. An annual special licence at the parish council is required (within 30 days of SIAC registration) and civil-liability insurance of at least €50,000. The dog must have a microchip and registration, and non-pedigree ones are sterilized. In short: yes, with a licence, insurance, a short leash and a muzzle.
📋 The rules
- 7 breeds potentially dangerous (Ordinance 422/2004)
- In public: leash up to 1 m + muzzle
- Annual special licence at the parish council
- Mandatory insurance of at least €50,000
- Microchip + SIAC registration; sterilization (non-pedigree)
🔓 Exceptions
- Officially-pedigreed dogs: exempt from sterilization
- Non-listed dogs: only fall under the regime if declared "dangerous" after an incident
- After aggression: the authority can seize the dog (at the owner's cost)
⚠️ Penalties & fines
Fines run from €750 to €5,000 (individuals) and €1,500 to €60,000 (companies) for breaching the dangerous-dog rules; serious cases can have criminal consequences. Beware a myth: the list has 7 breeds, not 8 — don't add the Mastiff or Boerboel, which belong to Spain's list (Royal Decree 287/2002). And not every big dog is legally "dangerous": the €50,000 insurance is mandatory only for listed dogs or those individually declared dangerous. To stay compliant: get the annual licence at the parish council, take out the insurance, always use a short leash and muzzle in public, and ensure microchip, SIAC registration and, where required, sterilization.

❓ Frequently asked
Which are the dangerous breeds in Portugal?
Seven: Brazilian Mastiff (Fila), Dogo Argentino, Pit Bull Terrier, Rottweiler, American Staffordshire Terrier, Staffordshire Bull Terrier and Tosa Inu, plus first-generation crosses. It's a myth to add the Mastiff or Boerboel, which are on the Spanish list, not the Portuguese one.
Do I have to use a leash and muzzle?
Yes, for dogs of the potentially dangerous breeds. In public, these dogs must be on a leash of up to 1 metre and wear a muzzle. These rules exist to prevent incidents. Non-listed dogs only become subject to them if individually declared dangerous after an incident.
Do I need a licence and insurance?
Yes. For a dangerous-breed dog, an annual special licence is mandatory, requested at the parish council within 30 days of SIAC registration, plus civil-liability insurance of at least €50,000. The dog must also have a microchip and registration, and non-pedigree ones are sterilized.
What's the fine for non-compliance?
Fines run from €750 to €5,000 for individuals and €1,500 to €60,000 for companies. In serious cases, such as attacks, there can be criminal consequences and seizure of the animal by the authority, at the owner's cost. Following the rules avoids these situations.
Is any big dog considered dangerous?
No. Only dogs of the seven listed breeds, and dogs individually declared dangerous after an incident, are subject to this regime. A big dog of another breed, with no history of aggression, isn't automatically "dangerous" and doesn't need the €50,000 insurance.
