VIDEO: Watch these furry surfers 'hang ten' at Oakland Coliseum

OAKLAND, Calif. (KGO) -- We're in the dog days of summer and it makes you want to hit the beach for a little surfing. Or you can just hit the Coliseum, where the dogs are hanging 10.

But these surf dogs aren't just here for fun.

"There's a serious side to this," said Lucy Pet Foundation President Joey Herrick. "This is all about ... our mission, which is to stop pet overpopulation. Eighty thousand dogs and cats a week are put to sleep in the United States because there's too many. People don't spay or neuter their pets."

And it wasn't just the pups surfing on Friday. A surfing cat was out there shredding, too -- on the only portable surf machine in the world. It's in Lot A at the Coliseum as the A's host Bark at the Park on Friday night.

It's your chance to bring your dog to the ballpark.
