I calmly walk my potentially dangerous dog down a street in Madrid. When going for a walk, an adult who came from behind throws his tail and the dog scratches his entire hand with his legs, the dog went with his homologated and appropriate muzzle and his leash of seventy centimeters. Will I have to answer for this damage? NO, because I fulfill the specific obligation regarding the dog of Law 50/1999, of December 23, on the Legal Regime of the Possession of Potentially Dangerous Animals and by article 1905 of the Civil Code.
Following the previous example, imagine that the dog was loose. Would there be responsibility? Yes, for breaching the obligation to carry it tied.
And if he were bound, but without a muzzle, and bit another animal or a person. Should the owner respond? Also, by failing to comply with the muzzle.
