It was the ultimate dog rescue last week in Sacramento, California. When Rowdy, a rat terrier went on a walk with his owner last Wednesday, he began barking like crazy. It turns out he was barking at another dog, Casper, stuck in an 8-inch drain pipe.According to ABC News 10, it's possible that Casper, a 15-year old miniature schnauzer, was stuck in the pipe for up to three days before Rowdy discovered the exhausted dog.Upon learning about their stuck pet, Casper's owners, the Herdandez family, ran to the local fire station.
