The Official ATAC Rules for Dogs on Rome Metro (2026)
ATAC (Azienda per la mobilità) is Rome’s public transport authority. They run the metro, buses, and trams—and they set the rules for dogs.
Here’s what ATAC’s official regulations say:
Dogs ARE Allowed If:
- Size: Small to medium-sized dogs only
- Equipment: Dog must wear a basket muzzle (museruola a paniere) AND be on a leash
- Hygiene: Dog must be in “adequate hygienic conditions” (translation: clean, not muddy/smelly)
- Ticket: You must purchase a standard ticket for your dog (same price as a human ticket)
- Metro cars: Dogs can ONLY ride in the first or last car of metro trains
- Limit: Maximum 2 dogs per vehicle
Dogs Are NOT Allowed If:
- Dog is aggressive or out of control
- Dog is not wearing a muzzle (even if they’re “friendly”)
- You’re trying to board a middle car on the metro
- You don’t have a ticket for the dog
Exception: Guide dogs for visually impaired passengers are exempt from ALL these rules (no ticket, no muzzle required, can ride in any car).
Do You Need a Ticket for Your Dog? Yes. Here’s How Much It Costs (2026)
This catches a lot of tourists off guard: Your dog needs their own ticket.
Current Ticket Prices (January-June 2026)
BIT (Biglietto Integrato a Tempo) - Standard Ticket:
- Price: €1.50
- Validity: 100 minutes on buses/trams OR one metro journey (including line changes)
- Where to buy: Ticket machines at metro stations, tabacchi (tobacco shops), newsstands
Source: ATAC official ticket page
Price Increase Coming July 2026
Starting July 1, 2026, the BIT ticket will increase to €2.00 (pending approval). This means:
- Before July 1, 2026: €1.50 per dog ticket
- After July 1, 2026: €2.00 per dog ticket
Source: ATAC tariff plan announcement
Do You Need to Validate Your Dog’s Ticket?
YES. Treat your dog’s ticket like a human ticket:
- Insert it into the yellow validation machine at the metro entrance
- Keep it with you during the journey (inspectors can check)
What if you don’t validate? Same penalty as riding without a ticket (we’ll cover that below).
Can You Use a Multi-Day Pass for Your Dog?
If you have a Roma 24H pass (€8.50) or Roma 72H pass (€18), your dog still needs their own separate ticket. The multi-day passes don’t cover animals.
Workaround for tourists: If you’re in Rome for multiple days and taking your dog on metro frequently, just buy individual €1.50 tickets each time. There’s no “dog pass” option.
Muzzle Requirements: What Type Do You Need? (And Where to Buy One)
Here’s where it gets specific: ATAC requires a museruola a paniere—a basket muzzle.
What’s a Basket Muzzle?
It’s the wire or plastic cage-style muzzle that covers your dog’s snout but allows them to:
- Pant
- Drink water
- Breathe comfortably
What’s NOT allowed:
- Fabric/nylon muzzles (the ones that strap the mouth shut)
- No muzzle at all (even if your dog is in a carrier)
Why Does ATAC Require Basket Muzzles?
Italian law (more on that below) requires muzzles on public transport to protect other passengers—but also to avoid restricting the dog’s breathing. Fabric muzzles can cause overheating, especially on Rome’s hot metro platforms in summer.
Where to Buy a Basket Muzzle in Rome
Before you arrive:
- Amazon.it (delivered to your hotel)
- Arcaplanet (Italian pet store chain with Rome locations)
- Zooplus.it (online pet store)
In Rome:
- Arcaplanet (multiple locations: Via Tuscolana, Via Prenestina, Cinecittà)
- Maxi Zoo (Via Tiburtina, Porta di Roma mall)
- Farmacia Veterinaria (Via Cola di Rienzo, near Vatican)
Price: €10-25 depending on size
Pro tip: If you’re flying to Rome, pack the muzzle in your luggage. Airport pet stores charge 2x the price.
What If Your Dog Won’t Wear a Muzzle?
Start muzzle training before you travel:
- Let dog sniff muzzle → treat
- Hold muzzle near face → treat
- Put muzzle on for 5 seconds → treat
- Gradually increase duration
Timeline: 1-2 weeks of daily practice
If your dog absolutely refuses? You can’t take them on the metro. ATAC staff will stop you at the gates.
Which Metro Cars Can Dogs Ride In? (First & Last Only)
This is the rule that surprises most people: Dogs can ONLY ride in the first or last car of the metro train.
Why This Rule Exists
ATAC wants to:
- Keep dogs away from crowded middle cars
- Give passengers with allergies/fear of dogs a choice
- Make it easier to manage if a dog causes issues
How to Find the First or Last Car
At the platform:
- Look for signs indicating train direction
- Stand at either end of the platform (not the middle)
- Wait for the train
- Board the end car
Rome Metro lines:
- Line A (orange): Battistini ↔ Anagnina
- Line B (blue): Laurentina/EUR Magliana ↔ Rebibbia/Conca d’Oro
- Line C (green): Pantano ↔ San Giovanni
Pro tip: The first/last cars are often LESS crowded anyway (most people board in the middle). You might actually prefer this.
What If the First/Last Car Is Full?
You have three options:
- Wait for the next train
- Ask ATAC staff if you can board a different car (they’ll usually say no)
- Take a taxi/bus instead
Can they fine you for being in the wrong car? Technically yes, though enforcement is inconsistent. Don’t risk it.
Size Restrictions: How Big Can Your Dog Be?
ATAC’s rules say “small and medium-sized dogs”—but what does that actually mean?
Official Policy
There’s no official weight limit posted on ATAC’s website. The rule just says “cani di piccola e media taglia” (small and medium-sized dogs).
Source: ATAC regulations
Unofficial Enforcement
Based on traveler reports and expat forums:
- Definitely allowed: Dogs up to ~15 kg (33 lbs) — Beagles, Cocker Spaniels, French Bulldogs
- Usually allowed: Dogs 15-25 kg (33-55 lbs) — Border Collies, Bulldogs, medium mutts
- Sometimes rejected: Dogs over 25 kg (55+ lbs) — Labs, German Shepherds, Golden Retrievers
- Rarely allowed: Giant breeds — Great Danes, Mastiffs, St. Bernards
What Determines “Too Big”?
It’s at the discretion of ATAC staff at the station. Factors they consider:
- Can the dog fit comfortably in the end car without blocking doors?
- Is the dog calm and under control?
- How crowded is the metro at that time?
Real talk: If you have a large dog (25+ kg), you might get turned away. Have a backup plan (taxi, walking).
Small Dogs in Carriers
If your dog is under 5 kg and fits in a carrier bag (max dimensions: 25x45x80 cm), you can:
- Skip the muzzle requirement
- Ride in any metro car (not just first/last)
- Still need a ticket

Italian Laws Governing Dogs on Public Transport
ATAC’s rules don’t exist in a vacuum—they’re based on Italian national laws.
Article 169 of the Italian Highway Code (Codice della Strada)
What it covers: Transport of animals in vehicles
Key provision (comma 6):
“È vietato il trasporto di animali domestici in numero superiore ad uno…”
Translation: It’s prohibited to transport more than one domestic animal unless they’re in appropriate cages/carriers or separated from the driver.
Why this matters for metro: While this law primarily applies to cars, it establishes the principle that animals on transport must be:
- Controlled (leash/muzzle)
- Not a danger to passengers or driver
- In conditions that don’t impede safe travel
Penalty for violation (in cars): €87-€344 fine + 1 point off license
Source: Article 169, Italian Highway Code
EU Regulation 1/2005 on Animal Transport
What it covers: Protection of animals during transport
Relevance: While this EU regulation primarily addresses commercial transport of livestock, it establishes baseline welfare standards:
- Animals must be able to breathe freely (why fabric muzzles aren’t allowed)
- Transport conditions must not cause injury or suffering
- Handlers are responsible for animal welfare during transport
Source: EU Regulation 1/2005
Legislative Decree 151/2007
What it covers: Penalties for violating EU animal transport regulations in Italy
Source: Italian implementation of EU Regulation 1/2005
What This Means in Practice
If you violate ATAC’s dog rules, you’re not just breaking company policy—you could be violating Italian transport law. Enforcement on metro is inconsistent, but the legal framework exists.
What Happens If You Break the Rules? (Fines & Enforcement)
Let’s talk consequences.
Riding Without a Dog Ticket
Penalty: Same as riding without a human ticket
- Fine: €50-€200 (depending on how many previous violations)
- Payment: Can be reduced if paid within 5 days
How they catch you: ATAC inspectors (controllori) randomly check tickets on metro. They’ll ask for your dog’s validated ticket.
Riding Without a Muzzle
Penalty:
- Immediate removal from metro (you and dog must exit at next stop)
- Possible fine (at inspector’s discretion)
How they catch you: ATAC staff at station entrances can stop you before you board if they see no muzzle.
Riding in the Wrong Metro Car (Not First/Last)
Penalty:
- Warning (first offense)
- Fine (repeat offense)
Enforcement: Inconsistent. Some inspectors don’t care; others are strict.
Dog Causes Damage or Bites Someone
Big problem. According to ATAC’s terms of transport:
“I viaggiatori accompagnatori degli animali sono responsabili per il risarcimento di eventuali danni provocati a persone, vetture o cose.”
Translation: You are financially responsible for any damage your dog causes to people, vehicles, or property.
This could mean:
- Medical bills if dog bites someone
- Property damage to metro car
- Legal liability
Solution: Make sure your dog is properly trained and under control before attempting metro travel.
Practical Tips for Riding Rome’s Metro with Your Dog (From Experience)
Here’s what they don’t tell you in the official rules.
1. Avoid Rush Hour (7:30-9:30 AM, 5-7 PM)
The metro is packed during rush hour. Even the first/last cars are crowded. Your dog will be stressed, people will be annoyed, and you’ll have a miserable time.
Best times to ride:
- Mid-morning (10 AM-12 PM)
- Early afternoon (2-4 PM)
- After 8 PM
2. Practice at a Quiet Station First
Before attempting Termini (Rome’s busiest station), try a quieter station like:
- Circo Massimo (Line B)
- Colosseo (Line B - though touristy, it’s less chaotic than Termini)
- EUR Magliana (Line B)
Get your dog comfortable with:
- Turnstiles
- Escalators/stairs
- Noise of arriving trains
- Crowded platforms
3. Bring Water
Rome’s metro platforms can get HOT (30°C+ in summer). Basket muzzles allow drinking, so bring a collapsible water bowl.
4. Have a Backup Plan
If ATAC staff turn you away (dog too big, no muzzle, metro too crowded), know your alternatives:
- Taxi: Most taxis accept dogs (ask driver first: “Posso portare il cane?”)
- Walking: Rome is walkable; metro isn’t always necessary
- Uber/FreeNow: Easier to find dog-friendly rides
5. Learn Key Italian Phrases
- “Il mio cane può salire?” = Can my dog board?
- “Ha bisogno di un biglietto per il cane?” = Does the dog need a ticket?
- “Dove posso comprare una museruola?” = Where can I buy a muzzle?
6. Check Your Hotel’s Location
Some Rome neighborhoods are metro-dependent (EUR, Parioli); others are walkable (Trastevere, Monti). If you’re traveling with a dog, book a centrally located hotel to minimize metro reliance.
7. Consider If Metro Is Even Necessary
Rome’s historic center (Colosseum, Trevi Fountain, Pantheon, Spanish Steps) is mostly not accessible by metro. You’ll be walking anyway.
When metro IS useful with a dog:
- Airport transfer (though Leonardo Express doesn’t allow dogs; take FL1 train instead)
- Reaching Vatican from far neighborhoods
- Going to EUR, Cinecittà, or outer neighborhoods
Guide Dogs & Service Animals: Special Rules (They’re Exempt)
If you’re traveling with a guide dog (cane guida) for visual impairment, the rules are completely different.
What’s Allowed for Guide Dogs
According to Italian Law 37/1974 and ATAC regulations:
- ✅ Free travel (no ticket required)
- ✅ No muzzle required
- ✅ Can ride in ANY metro car (not just first/last)
- ✅ Access to all public spaces (restaurants, museums, etc.)
Source: ATAC guide dog regulations
What Counts as a “Guide Dog”?
In Italy, a guide dog is specifically:
- A dog trained to assist visually impaired people
- Certified by an official training organization
- Wearing a harness/vest identifying them as a working dog
What does NOT count:
- Emotional support animals (ESAs)
- Therapy dogs
- Psychiatric service dogs
US travelers, note: Italian law is stricter than US ADA. Only guide dogs for the blind are guaranteed access. Other service animals are at the discretion of individual businesses/transport authorities.
Proving Your Dog Is a Guide Dog
You may be asked to show:
- Official certification from training organization
- Harness/vest with identification
- Disability documentation (though asking for this is controversial)
In practice: Most ATAC staff will see the harness and wave you through without questions.
Dogs on Rome Buses & Trams: Are the Rules the Same?
Good news: If you’ve mastered the metro rules, buses and trams are easier.
Dogs on ATAC Buses
Same rules as metro:
- ✅ Basket muzzle + leash required
- ✅ Ticket required (€1.50/€2.00)
- ✅ Small/medium dogs only
- ✅ Max 2 dogs per bus
Difference from metro:
- ❌ No restriction on which part of bus you board
- ✅ Can sit anywhere (though try to avoid blocking aisles)
Tip: Buses are often MORE crowded than metro. If your dog is nervous around people, metro (first/last car) might actually be better.
Dogs on Rome Trams
Same rules as buses:
- Muzzle, leash, ticket required
- Can board anywhere on tram
Which tram lines are most dog-friendly:
- Tram 8 (Trastevere ↔ Largo Argentina): Scenic, less touristy
- Tram 3 (Valle Giulia ↔ Trastevere): Runs through parks (Villa Borghese)
- Tram 19 (Gerani ↔ Piazza Risorgimento): Useful for Vatican area
FAQ: Your Top Questions About Dogs on Rome Metro
Can I bring my dog on the Leonardo Express to/from the airport?
No. The Leonardo Express (direct train Fiumicino Airport ↔ Termini) does not allow dogs except guide dogs.
Alternative: Take the FL1 regional train instead:
- Dogs allowed (with muzzle + leash + ticket)
- Same route (Fiumicino ↔ Termini)
- Cheaper (€8 vs €14)
- Takes 10 minutes longer
Source: Trenitalia pet policy
What if my dog is too big for the metro?
Your options:
- Taxi: More expensive (€15-30 depending on distance), but most accept large dogs
- Walk: Rome is compact; many areas are walkable
- Uber/FreeNow: Filter for drivers who accept pets
- Dog-friendly car rental: Rent a car for day trips outside Rome
Do I need a muzzle for my tiny Chihuahua?
Technically yes—if they’re walking on leash.
Workaround: Put your Chihuahua in a carrier bag (under 5 kg, max 25x45x80 cm). Then:
- No muzzle required
- Can ride in any metro car
- Still need a ticket
Can I bring my dog on the metro at night?
Yes, as long as metro is running:
- Mon-Thu: Until 11:30 PM
- Fri-Sat: Until 1:30 AM (extended hours)
- Sunday: Until 11:30 PM
Night buses (linee notturne): Dogs allowed with same rules (muzzle, leash, ticket).
What if my dog has an accident on the metro?
You are responsible for cleanup. Bring:
- Poop bags
- Paper towels
- Disinfectant wipes
If it’s a major mess, alert ATAC staff. They can call a cleaning crew (and may fine you).
Are cats allowed on Rome metro?
Yes, but different rules:
- Must be in a carrier/cage (max 25x45x80 cm)
- No muzzle required (they’re in a carrier)
- Need a ticket (€1.50/€2.00)
- Can ride in any metro car
Can tourists bring dogs to Rome’s tourist sites?
It varies:
- ✅ Allowed: Colosseum (outdoor areas), Roman Forum, Spanish Steps, Trevi Fountain (outdoor), parks
- ❌ Not allowed: Vatican Museums, Sistine Chapel, most churches, Borghese Gallery
Always check ahead. Many museums have “no pets” policies.
Is Rome dog-friendly compared to other European cities?
Yes! Rome is more dog-friendly than many European capitals:
- Dogs allowed in most outdoor cafes/restaurants
- Many hotels accept dogs
- Parks everywhere (Villa Borghese, Villa Ada)
- Beaches near Rome allow dogs in designated areas
More dog-friendly than: Paris, London Less dog-friendly than: Berlin, Copenhagen
Where can my dog poop in Rome?
Designated dog areas:
- Villa Borghese (multiple dog parks)
- Villa Ada
- Parco degli Acquedotti
- Caffarella Park
Rules:
- Always pick up poop (fine: €50-300)
- Use green waste bins (marked “Cestino rifiuti organici”)
- Don’t let dog poop near monuments/fountains
The Bottom Line: Yes, Dogs Can Ride Rome Metro (If You Follow the Rules)
Here’s what you need to remember:
Before you go:
- Buy a basket muzzle (€10-25)
- Practice muzzle training (1-2 weeks)
- Budget for dog tickets (€1.50 each trip, €2.00 starting July 2026)
At the station:
- Buy ticket at machine or tabacchi
- Validate ticket (yellow machine)
- Head to first or last car platform position
On the metro:
- Board first/last car only
- Keep dog on leash, wearing muzzle
- Avoid rush hour (7:30-9:30 AM, 5-7 PM)
- Have ticket ready for inspectors
If something goes wrong:
- Staff refuse entry → Ask politely why, have backup plan (taxi)
- Dog is stressed → Exit at next stop, walk or take taxi
- Inspector asks for ticket → Show validated dog ticket
Is it worth it?
Honestly? If your dog is:
- ✅ Small/medium (under 20 kg)
- ✅ Calm in crowds
- ✅ Muzzle-trained
Then yes, Rome’s metro is navigable with a dog.
But if your dog is:
- ❌ Large (25+ kg)
- ❌ Anxious/reactive
- ❌ Not used to muzzles
You might be better off walking or taking taxis. Rome’s historic center is compact—you don’t need the metro for most tourist sites.
Either way, now you know the rules. No more guessing at Termini station with a confused dog and annoyed ATAC staff.
Buon viaggio! (Safe travels!)
