Hiking with a dog in Greece: rules and tips

The Pezoparea team · Updated 4 November 2026 · 6 min read

You can hike with a dog on most Greek trails, on a leash, as Law 4830/2021 requires. In the core of Parnitha National Park dogs are banned even on a leash. Watch out for sheepdogs, pine processionary caterpillars in spring and summer heat, and always ask the organizer before bringing a dog on a group outing.

What does Greek law say about dogs on trails?

Greece's pet welfare law, Law 4830/2021, says that on walks the owner must keep the dog on a leash and close by to prevent accidents (Article 9, Government Gazette A' 169/2021). Dogs must also be microchipped and registered.

On a mountain, the leash isn't just a formality. There are flocks, sheepdogs, wild animals and drop-offs, and a dog running ahead can get into trouble in seconds.

Where are dogs banned in Greece?

Before visiting any protected area, check the current rules with its management body, because regulations change.

Can I bring my dog on an organized group hike?

Not every organizer allows it, especially when transport is by coach or the route crosses a protected area. Ask before you sign up. If they say yes, keep the dog leashed, near the back of the group, and away from people who are nervous around dogs.

What should I do if I meet sheepdogs?

Greek sheepdogs are doing their job: guarding the flock. A loose dog near a flock can trigger an attack. Advice for hikers in protected areas (EPIRUS Online):

• Keep your dog on a short leash, right beside you
• Don't run, shout or stare the dogs in the eye
• Walk around the flock in a wide arc at a steady pace
• If the dogs come close, stop and stand still. They usually lose interest
• A trekking pole helps keep distance, but never swing it at them

What dangers do dogs face on Greek mountains?

• Pine processionary caterpillars: their toxic hairs cause swelling of the tongue and mouth. Risk peaks from February to July. If your dog touches one, go straight to a vet.
• Sandflies and leishmaniasis: leishmaniasis occurs throughout Greece, and sandflies are active from spring to autumn, mainly at dusk. Ask your vet about vaccination and repellents.
• Ticks: check ears, paws and belly after every hike.
• Heat: dogs don't sweat like we do. The American Kennel Club's chief vet suggests the hand test: hold your palm on the ground for 10 seconds; if it's too hot for you, it's too hot for paws.

In summer, choose routes with shade and water and set off at first light. Flat-faced breeds like bulldogs overheat much more easily.

What should I pack for my dog?

• Leash and harness (not just a collar)
• Water and a collapsible bowl: don't count on springs in summer
• Poop bags
• Some food or treats for energy
• Tick tweezers and a bandage for paws
• An ID tag with your phone number
