The Mercy hitmaker reportedly learned Bronx was going to be put down by officials at an Orange County adoption centre in California after they failed to find him a home, so the Welsh star reached out to employees at the Los Angeles shelter Ace of Hearts and donated $1,000 (£625) to help them save the dog.
Bronx was moved to the shelter at the end of March (15), where Fuentes fell in love with the animal and decided to foster him, so he will be fully trained by the time he is put back up for adoption.
The Cuban beauty, who is covering all costs for Bronx's training, introduced her new furry friend to fans on Instagram last week (ends03Apr15), writing, "I'm a foster mom to this gorgeous boy BRONX Getting him ready for a forever home. He's such sweet, smart, goofy puppy (around 1yr old). If anyone in the LA area wants this baby, I'll post details soon."
