Jennie Garth actress reality star A Little Bit Country

The dog days technically haven't begun yet, but Jennie Garth and her pooch Black Pearl are already scorched.

The actress and her dog looked parched after a run in Beverly Hills yesterday, stopping at a local park to hydrate. You just can't take the girl out of 90210!

The star of the new CMT reality series Little Bit Country is most certainly keeping off the 30 pounds she lost since divorcing ex-husband Peter Facinelli in 2011.

"I've been working out really hard," she told Health magazine in January. "I've been weight training with a trainer three days a week. ... I really never sit down. I mean, that's basically the secret. It's just not sitting around."

Well, the secret's out now.
