🇪🇸 Potentially dangerous dogs in Spain
Spain classifies some dogs as perros potencialmente peligrosos — PPP — and owning one means a licence from your town hall, a liability policy and a muzzle in the street. The rules are older than most of the internet says, and the 2023 animal-welfare law changed less about them than the headlines suggested. Here is where it actually stands.
The law that still governs it
Two texts do the work. Ley 50/1999 created the category and the licence; Real Decreto 287/2002 filled in which dogs it catches. Both are still in force.
This is worth saying plainly because a lot of coverage of Ley 7/2023, the animal-welfare law in force since September 2023, reported that breed lists were on the way out. During its passage there was a real proposal to drop the list and judge each dog on a sociability assessment instead. It did not survive into the final text. The PPP category, the list and the licence all stayed exactly where they were.
The eight breeds — and the rule that catches everything else
Annex I of RD 287/2002 names eight breeds and their crosses. That list is the part everyone knows. Annex II is the part that surprises people: a dog of any breed, or no breed at all, is a PPP if it has all or most of a set of physical traits — strong musculature and an athletic build, a short coat, a chest of 60–80 cm, 50–70 cm at the withers, over 20 kg, a large cuboid head with a broad skull and heavy jaws, and a short, wide, muscular neck.
So a big-boned mixed breed from a shelter can land in the category without a single listed breed in its ancestry, and a slight, 18 kg dog of a listed breed is still a PPP because the breed name alone puts it there. If you are unsure which side of the line your dog falls on, the town hall that issues the licence is also the body that decides.
The licence
It is municipal. You apply to the ayuntamiento where you live, it lasts five years, and it is renewable. What you have to produce is consistent across the country: proof you are 18 or over, a criminal-record certificate clear of the offences the law names, a certificate of physical capacity and psychological aptitude from an authorised centre, and the insurance below.
The licence belongs to the handler, not the dog. Anyone who walks the dog in public needs their own — which is the detail that catches families out, because the partner or the teenager taking the dog round the block is committing the offence, not the person whose name is on the paperwork.
The insurance
Third-party liability cover is compulsory and the national floor is 120,000 €. Several comunidades set it higher — Madrid and Catalonia are the ones usually named — so check your own before you buy the policy rather than after.
Read what the policy actually covers, too. A general pet policy is often not a PPP policy, and some insurers exclude the listed breeds outright or require the licence number on the certificate.
In the street
Three rules, and they are the ones that get enforced: a muzzle suited to the dog's breed, a non-extendable lead under two metres, and one PPP per handler. No flexi-leads, no two dogs on one walk, no under-18s holding the lead.
Fines start at the level that makes the licence look cheap, and the offence is the handler's. Carrying the licence and the insurance certificate on the walk is not legally required everywhere, but a photo of both on your phone settles a police check in a minute rather than an afternoon.
Where your región changes it
The eight breeds are a floor, not a ceiling. Galicia and Extremadura both extend the list — the Presa Canario, the Mastín Napolitano and the Dóberman appear on regional lists that the national one leaves off. Catalonia and the País Vasco run their own regimes on top of the state framework rather than simply repeating it.
The practical consequence is that a dog can be a PPP on one side of a regional border and not the other, and moving house can hand you a licence application you did not have before. The autonomous community's own decree is the authority; nothing on this page overrides it.
What Ley 7/2023 did change
It changed a lot for every dog owner and almost nothing for PPP owners specifically. Two of its provisions matter most and neither is enforceable yet: a training course that every dog owner will have to complete, of indefinite validity, and compulsory liability insurance for every dog regardless of breed.
Both are written into the law and both wait on the reglamento that sets the detail — the course platform and the minimum sum insured. Until that lands, a non-PPP owner has no course to sit and no figure to insure to. When it does, the gap between owning a PPP and owning any other dog narrows considerably.
Questions
Which breeds are PPP in Spain?
Real Decreto 287/2002 names eight and their crosses: Pit Bull Terrier, Staffordshire Bull Terrier, American Staffordshire Terrier, Rottweiler, Dogo Argentino, Fila Brasileiro, Tosa Inu and Akita Inu. Some comunidades add to that list, so the regional rule can be stricter than the national one.
Did Ley 7/2023 abolish the PPP list?
No. The proposal to replace breed lists with individual sociability assessments was dropped before the final text. Ley 50/1999 and RD 287/2002 remain in force, and so do the licence, the insurance and the muzzle.
How much insurance does a PPP need?
The national minimum is 120,000 € of third-party liability cover. Some comunidades, Madrid and Catalonia among them, require more, so check the regional figure before buying.
Can a mixed-breed dog be a PPP?
Yes. Annex II of RD 287/2002 classifies any dog with all or most of a list of physical traits — over 20 kg, 50–70 cm at the withers, a 60–80 cm chest, short coat, heavy cuboid head — whatever its ancestry.
Who needs the licence — the owner or whoever walks the dog?
Whoever is holding the lead. The licence is personal, so every person who takes the dog out in public needs one of their own, and it is the handler who commits the offence if they do not have it.
How long does a PPP licence last?
Five years, and it is renewable. It is issued by the town hall of the municipality where you live, not by the region or the state.
