Spanish officials have relented and say a couple who started an online petition to be allowed 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 Wednesday the case had been reviewed and the couple would 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.
