Pet Laws in Buenos Aires

There are a number of laws related to owning pets in Buenos Aires. It should be noted that the laws concerning animals in Buenos Aires City and the Province of Buenos Aires mention only dogs and cats when referring to domestic pets. Some of the main regulations are as follows:

  • Vaccination of dogs and cats against rabies is compulsory. Additional vaccination requirements should be checked with a veterinary practitioner
  • Animals must be kept on a leash in public
  • Dogs and cats are not allowed in shops, except for guide dogs.
  • Guide dogs are allowed on public transport provided there is adequate room for them
  • It is forbidden to sell or give away pets in public places; the sale of dogs and cats must be carried out in shops intended for that purpose
  • All dog owners must register their dog with the Dog Register of each Municipality, although in practice this is rarely done
  • Dog and cat refuges/shelters must be approved by the local authority. Vets must oversee the activity, and hygiene and food regulations must be observed. A register of the animals held in the shelter or refuge must be kept

Animals do not have to be microchipped or have a tattoo.


Dogs and cats must be vaccinated according to plans in force in each suburb of the city. As the need for vaccinations may vary depending on the breed and age of the pet, it is recommended to consult a veterinary practitioner on this issue.
