The number of people in Barcelona who live with dogs has not stopped growing in recent years, to the point that, according to the City Council, there are already over 180,000 dogs living in the city (174,316 of them identified with a chip, according to data from the College of Veterinarians), which is considerably more than, for example, the 171,863 children under 12 years of age who are registered on the census. But, despite the growth, the city has not yet resolved an important aspect for the coexistence with pets in squares and streets: defining where they can and cannot be let off the leash. This issue has been dragging on since 2014, when the Council modified the ordinance for the protection and keeping of animals to allow police to fine dog-owners whose pets were off the lead. At that time it was already agreed that the measure, which was to involve fines of at least €100, could not be enforced immediately because the city at that time was not ready: it was necessary to ensure that there were sufficient spaces for the recreation of dogs before prohibiting them to go off the lead.
