Can I keep a potentially dangerous dog?
Yes, but with a licence, insurance and safety measures. Keeping a potentially dangerous dog (PPP) —certain breeds and dogs with specific traits— requires strict conditions. You need a municipal licence, for which you must be of legal age, provide a criminal-record certificate, an aptitude certificate (physical and psychological) and take out civil-liability insurance with a minimum cover of €120,000. The dog must be registered in the municipal PPP register and microchipped. In public it must always wear a muzzle and a non-extendable leash under 2 metres, and only one PPP per person may be walked. The new animal-welfare rules keep, for now, this regime.
📋 The rules
- Municipal licence required to keep a PPP
- Requirements: of age, criminal record and aptitude certificate
- Insurance with a minimum cover of €120,000
- Registration in the municipal register and microchip
- In public: muzzle, leash <2 m and one dog per person
🔓 Exceptions
- Each region and town hall may add requirements or breeds
- The licence is renewed periodically (usually every 5 years)
- A sociability test is planned that may adjust the muzzle requirement
⚠️ Penalties & fines
Keeping a PPP without a licence, without insurance or walking it without a muzzle and proper leash is an offence that can carry high fines (the most serious, several thousand euros), the seizure of the animal and even its removal. Liability for the damage the dog causes falls on the owner, hence the insurance requirement. Before getting a PPP, check the specific requirements at your town hall (they can vary by region) and arrange the licence and insurance before keeping it.
