A couple who started an online petition to be allowed to call their newborn son the Spanish word for Wolf will now be permitted to do so.
Nako and Maria Javierre launched the campaign after a registry office in Madrid last month refused to accept the name, arguing it could be "offensive" for their son.
They were later told Lobo (Wolf) was a surname in Spanish and could cause confusion.
But national registry office chief Javier Gomez Galligo said the case has been reviewed and the couple will be allowed to name the child Lobo.
The parents said they decided on the name because of "our love for this animal".
The petition received some 25,000 supporters and was widely reported on around the world.
