On the buses and trolleybuses of Vilnius, any public transport passenger can transport his/her pet/animal in a special dedicated container (e.g. a box, a basket, etc.) free of charge. If a larger animal, which does not fit in any container, is transported, it can ride without a container.
The passenger must have the documents specifying the pet’s vaccination marks and the pet must wear a muzzle (except for dogs whose breed is not suited for muzzles) and kept on a leash no longer than 0.5 metres. These criteria are specified in the Regulations of Transportation of Passengers and Luggage on Buses and Trolleybuses in Vilnius City.
Remember that if an animal polluted the interior of a bus or a trolleybus the passenger who is carrying it must immediately clean the dirtied area of the interior. Moreover, the passenger is responsible for the harm caused by the animals it is carrying to the health, lives, property, and peace of the other passengers and must reimburse it and also follow the approved Regulations of Animal Handling in the territory of Vilnius City Municipality.
