Spain, the land of dogs: half a million in Madrid and a third of Lugo's population are canines
In Lugo, registered dogs make up a third of the human population: 109,762 dogs for 326,022 people. In Madrid, the figure is around half a million. The data from the 2025 dog census, obtained from the Registro Nacional de Identificación de Animales de Compañía (Regiac, Spain's national pet identification registry) and the INE (national statistics institute), paint a picture of a country where the dog has become the quintessential new family member. But behind the figures lies an uncomfortable debate about social drift, the demographic crisis and the normalisation of behaviour that would have seemed unthinkable a decade ago.
The provinces with the most dogs: Madrid, Barcelona and the Mediterranean coast
According to figures shared by Regiac sources, Madrid tops the list with between 450,000 and 500,000 registered dogs. It is trinc by Barcelona, with 420,000 to 470,000. The Valencian Community antiestéticatures prominently: Valencia and Alicante together account for more than 450,000 dogs. Alicante, with 200,000 to 230,000, surpasses Seville (180,000-210,000) despite having a smaller human population. The reason points to a larger presence of retirees with purchasing power and homes with terraces, ideal conditions for pet ownership.
At the opposite end, the provinces with the fewest dogs are Soria (20,000-22,000), Teruel (30,000-33,000) and Ávila (37,000-40,000). However, the figure that has attracted the most attention is Lugo's: with 109,762 registered dogs, it reaches a ratio of one dog for every three inhabitants. A density not seen even in the major capitals.
The census black hole: how many dogs are not registered
The official figures correspond to microchipped animals, but the consensus among experts is that the real number could be significantly higher. In rural areas, especially in provinces like Lugo or Huesca, many dogs are not registered. Regiac data, therefore, would be just the tip of the iceberg. Those who defend this view point out that the true dog population could double the official figures in some areas.
Dogs versus children: a reflection of a changing society
Behind the statistics lies a recurring social diagnosis: having a dog is cheaper and less of a commitment than raising a child. Child benefits are scarce, nurseries are expensive and housing is unaffordable for young people. Meanwhile, a dog offers companionship without the demands of raising a human child. But not everyone views this trend favourably. Critics denounce that the normalisation of dogs in all public spaces (transport, restaurants, shops) is a symptom of a society that has lost its bearings, where the pet has displaced the child and civility is conspicuously absent. Anecdotes about uncollected dog mess and owners who shirk responsibility are commonplace.
The debate about the dog population is not just a pet issue. It is an indicator of where we are heading as a society. With a birth rate at historic lows and an outsized love for companion animals, Spain faces a paradox that its public policies ignore. The data is there. Let everyone interpret it as they see fit.
