As a dog lover, I was curious about what dogs I would see when visiting Paris. I saw fewer than I expected but those I did I encountered in different locations, from promenading with their owners along the wonderful, walkable streets to riding comfortably in shoulder bags.
Acording to Per Traveler: “Parisians love spending time with their pets, and it is evident in how pet-friendly the city is. Dogs in Paris are allowed on all public transport including the metro, the subway, the commuter trains and buses.
Service dogs can travel for free on all forms of transport, and large dogs need a ticket to travel. Small dogs can travel in a bag or dog carriers and do not need a ticket. Larger dog breeds must be on a lead and muzzled when they are travelling on public transport. Parisian taxis can choose to accept or refuse to take your dog in the car; it is a good idea to mention your dog when you book your cab.”
One large border collie/lab mix was comfortable laying on the floor of one of the metro coaches between riders’ feet and legs. Even beggars on the street had their pups bundled up in blankets on their legs.
Other chiens rode the metro tethered with leases to their ownership.
Dogs were always on leashes. I didn’t see any dog parks like there are in the US. But people and dogs seem happy and comfortable walking around the cobbled streets and cafes no matter how crowded they are.
