MERCEDES - A young girl heartbroken over the loss of her pet has a new little friend tonight.  On Friday, 7-year-old Desiree Trevino's pet Chihuahua Chiquita was stolen from her home.

Victor Olivo saw the story on CHANNEL 5 NEWS and wanted to help.  Today he donated his Chihuahua, Gazormous, to Desiree. 

"It was given to me as a gift, because I'm asthmatic.  It's supposed to cure me.  But if it can cure someone's sadness... I have a doctor for that," says Olivo. 

One word comes to Desiree's mind when describing her new pet.  She says she is "happy."

Oliva says that's what truly matters. 

"It cannot replace her dog, but it can at least kinda give her a little bit of a new start with a new pet.  That's all I really want, for the child to be happy," says Olivo.

Desiree's mother, Yadira, says they haven't given up on finding Chiquita.  She says, "We're keeping our faith that maybe somebody out there might be kind enough to return her back to us."
