When a dog is found wandering the streets in Spain without its owner, those who come across it often face the same question: Are you allowed to simply keep the dog? And what does the law require? Clear legal regulations provide guidance – and they concern not only animal lovers, but also local authorities and municipalities.
Since the reform of animal welfare legislation in Spain, animals are no longer regarded merely as property, but are legally recognised as sentient beings with special protections. This change affects not only the way animals are kept, but also how stray or unaccompanied dogs are handled.

Police and Municipal Responsibilities
If someone finds a dog alone on the street or without an identifiable owner, they should first alert the police or the local municipal authority. In many Spanish municipalities, the Policía Local or the city’s animal welfare service is obliged to collect the animal and take it to a designated centre, where it is provided with initial care and registered.
There are two reasons for this: on one hand, it prevents private interventions or “taking” the animal without coordination with the authorities. On the other hand, it is the responsibility of municipalities to receive and protect lost or abandoned animals until the rightful owner is identified or the animal is otherwise rehomed.
Microchip, Deadlines, and Possible Adoption
Modern animal shelters scan the dog for a microchip – a mandatory form of identification legally required for dogs in Spain. If a registered owner is found, they are contacted immediately.
If a dog does not have a microchip, or if no rightful owner comes forward within the legal period (typically between 20 and 30 days), this status ends, and the dog can legally be rehomed or adopted. The prerequisite is always that the authorities have been properly involved.
No Unauthorised Claims of Ownership
A key aspect of Spanish law is that you cannot simply keep a stray dog just because it appears alone on the street. Bypassing the official process through the police and an animal shelter can be considered unlawful appropriation, with potential legal consequences. These include civil claims by the owner for the return of the animal, as well as possible compensation claims. In certain cases, the criminal offence of “apropiación indebida” (unlawful appropriation) may also apply, which can result in fines. Administrative penalties are also possible if reporting and registration obligations are not followed.
Background: Protection of Animals and Society
The clear regulation serves two purposes: on one hand, it provides animals with a minimum level of protection and a fair chance to be returned to their owner. On the other hand, the rules prevent individuals from deciding an animal’s fate without a legal basis. Experts from animal welfare organisations see this as a significant step forward in the management of pets in public spaces.
