Dogs in Rome: Microchip, Leash Rules, and Everything Else You Need to Know

In a nutshell

If you own a dog in Rome, four basic rules apply to everyone: microchip within the first months of life (or within 30 days of acquiring the dog); leash at all times in public with a maximum length of 1.5 metres; muzzle always carried on your person even when not worn; and waste picked up in every public space without exception. Breaking these rules means fines starting at €25 and potentially exceeding €500.

At a glance

Microchip cost	€20–40 at the ASL (Azienda Sanitaria Locale — your local public-health authority) veterinary service; €35–60 at an accredited private vet. Change of ownership: free.
Timeline	Microchip required within 60 days of birth or 30 days of acquiring the dog. Implantation is immediate. Registry entry: 7–15 days.
Where in Rome	Veterinary services at ASL Roma 1–6. Accredited private vets registered with the Anagrafe Canina Regionale del Lazio (Lazio regional canine registry).
Documents	Owner's ID, Codice Fiscale (Italian tax ID), dog physically present, proof of origin if available.

Microchip: it's the law

The microchip is a rice-grain-sized device implanted under the skin at the back of the neck. It contains a unique 15-digit number that identifies the animal in both the regional and national canine registries, making it possible to trace the owner if the dog is lost, bites someone, or is abandoned.

The requirement applies to every dog, regardless of breed or size:

• Puppies born in Italy: within 60 days of birth.
• Dogs acquired by purchase, adoption, or gift: within 30 days.
• Dogs brought in from abroad: within 30 days of arriving in Italy. Dogs from EU countries often already have a European microchip — in that case you only need to register them with the Anagrafe Canina del Lazio.

The fine for failing to microchip or register a dog can reach €165.

Where to get the microchip in Rome

You have two main options.

ASL veterinary service (public option): costs around €20, varying slightly by ASL. Includes both implantation and registration with the canine registry. You need to book by phone or online through your ASL's website.

Veterinary service contacts in Rome:

• ASL Roma 1 — Sede Borgo Santo Spirito, tel. 06 68352571 — aslroma1.it
• ASL Roma 2 — Via Filippo Meda, tel. 06 51005404 — aslroma2.it
• ASL Roma 3 — Via Casal Bernocchi, tel. 06 56487270 — aslroma3.it
• ASL Roma 4 — Civitavecchia, tel. 0766 591211
• ASL Roma 5 — Tivoli, tel. 0774 7011
• ASL Roma 6 — Albano, tel. 06 93271

Accredited private vet: costs between €35 and €60, which covers both implantation and submission of data to the registry. Before booking, confirm that the vet is accredited with the Anagrafe Canina Regionale del Lazio.

After the procedure the vet gives you a registration certificate. The data is transmitted to the Anagrafe Canina Regionale del Lazio and to the National Database at the Ministry of Health.

When you must report changes

Within 15 days of any of the following events, you must notify the ASL or the canine registry: sale, donation, or transfer of the dog to someone else; the dog's death; loss or theft; finding someone else's stray dog; change of the owner's address. All communications are free, either in person at the ASL desk or through the Anagrafe Canina Lazio online portal where available.

Important: if you transfer ownership without registering the change, you remain the legally responsible owner in the event of any incident.

Leash and muzzle: the rules in public

The Ministerial Order of 23 March 2009 (commonly called the "Martini" ordinance), renewed annually, sets the national rules for dogs in public spaces throughout Italy.

Leash: required in all public spaces and places open to the public. Maximum length is 1.5 metres. Retractable leashes must be locked at this length — extending them to full length is not permitted. Fine for violation: €25 to €500.

Muzzle: does not have to be worn at all times, but must always be carried on your person — in a pocket, bag, or clipped to the leash. It must be put on when requested by a law-enforcement officer or public-transport staff, when travelling on public transport (bus, metro, tram, train, taxi), in crowded places where there is a risk to people or other animals, and if the dog has a recorded history of biting.

The only exception to the leash rule is in designated enclosed dog parks, where dogs can move freely under their owner's supervision.

Dogs on ATAC public transport

ATAC (Rome's public-transport operator) has the following rules. Small dogs in a closed carrier travel free. Medium and large dogs must wear a muzzle and leash, and the owner must buy a standard ticket for the animal. Guide dogs for the visually impaired are always admitted free and do not need a muzzle.

Dog parks in Rome

Rome has over 100 recognised dog parks managed by the Comune (city hall / municipality), spread across all its fifteen districts (Municipi). The most well-known are in Villa Borghese (3 areas), Villa Doria Pamphilj (2 areas), Villa Ada, Villa Torlonia, Parco Nemorense, Parco del Pineto, Parco degli Acquedotti, and Parco della Caffarella.

Picking up after your dog

Rome's municipal regulations require you to clean up after your dog in all public spaces. Carry bags with you at all times and pick up without exception. Waste goes in the general refuse bin. In some areas — particularly the historic centre and busy pedestrian zones — you are also expected to rinse away urine with a bottle of water. Fine for non-compliance: €25 to €258.

Mistakes to avoid

1. Thinking the microchip is optional. It is a legal obligation with a fine of up to €165. No exemptions for breed or size.
2. Buying puppies without a microchip and documentation. Anyone selling puppies without a certificate of origin and a microchip is often operating outside the law. Walk away.
3. Not registering a change of ownership. Until the transfer is recorded, the previous owner is legally responsible for any incident the dog causes.
4. Using a retractable leash without locking it. The 1.5-metre limit is measured at full extension — the lock must be engaged, not just held in your hand.
5. Leaving the dog locked in the car in summer. This puts the dog at serious risk of death and exposes the owner to a criminal complaint for animal cruelty under art. 544-bis of the Italian Penal Code.

Special cases

Adoption from a shelter: dogs adopted from Rome's municipal shelters — including the Canile Muratella at Via Portuense 798 and the Canile della Magliana — are already microchipped and registered. You only need to register the change of ownership at the ASL within 15 days, free of charge.

Dog from abroad: if your dog comes from an EU country and already has a European passport, microchip, and valid rabies vaccination, you only need to register it with the Anagrafe Canina del Lazio within 30 days. Dogs from non-EU countries require a health certificate from the country of origin, rabies-antibody titration, and a microchip.

Lost dog: report the disappearance immediately to the ASL veterinary service or the Polizia Locale (city police). Check the Canile Muratella, which is where stray dogs found in the city are usually taken. Any vet can scan a found dog's microchip on the spot.

Bite incident (person or other animal): you must report it to the ASL within 24 hours even if the wound is minor. The ASL will summon the dog for a 10-day veterinary observation period. The owner may be required to obtain the patentino cinofilo — a 6–10 hour dog-handling course provided free by the ASL.

Dangerous breeds: since 2009, Italy no longer maintains a list of dangerous breeds. The Martini ordinance abolished the previous breed-specific list. Additional restrictions (muzzle at all times, patentino, third-party liability insurance) apply to dogs that have been reported as difficult following a bite incident, regardless of breed.

Reporting animal cruelty: contact the Numero Verde Nazionale Polizia Animali (800 253 608), the Carabinieri Forestali (1515, 24-hour line), the Polizia Locale Roma Capitale (06 67691), LAV Lazio (06 4461325), or ENPA Roma (06 5896309).
