The Guardia Civil have launched an investigation after he was found with his face and limbs ripped to shreds, injuries that are consistent with fighting off a pack of dogs.
Officers said the wounds suggest he put up a fierce struggle before bleeding to death.
Investigators visited nearby houses where they found that one neighbour had five dogs – all pitbull and bullterrier mixed breeds – which are classified as ‘potentially dangerous breeds’ under Spanish law.
Despite not seeing blood stains on the dogs, officers noticed that one of the animals had a wet coat, as if it had just been washed down, although the owner claimed it had fallen into the swimming pool.
Police said only one of the dogs had a chip and that the owner did not have the correct permits for the dangerous breeds.
Under Spanish law, owners of ‘perros potencialmente peligrosas’ (PPP) – which include pit bull terriers, rottweilers, Staffordshire bull terriers, American Staffordshire terriers, dogo argentinos, fila brasileiros, Tosa Inus, and Akita Inus – must have a licence and keep their dogs muzzled and on a tight leash when outdoors.
