Selena Gomez and Jake T. Austin helped feed and rescue stray dogs for the 'Do Something' charity at the beach in Puerto Rico on Saturday. Sel wrote about the emotional day on her MySpace: 'I'm honored to be the new ambassador for DoSomething.org! The last time I was in PR shooting Princess Protection Program we noticed all of these stray dogs and puppies. We ended up finding out that Puerto Rico has a 'dead dog beach" its sounds worse than it is but people actually kills dogs for fun here. Photos: PacificCoastNews. Adding 15+ more soon.
