Rebecca Gayheart and Eric Dane

My heroes! Eric Dane and his wife Rebecca Gayheart saw a little pooch on the mend from a surgery at an adoption event while shopping yesterday. Looks like he pulled at their heartstrings because they adopted him on the spot. Love them!

Rachel Bilson

Rachel Bilson and her little sister Hattie took her dog Thurman Murman for a walk before meeting up with their grandma in Studio City yesterday. Rachel seems to be one of the most attentive and responsible celebrity pet owners. Nice job!

Rihanna has quite a gentleman on her hands. Not only did her boyfriend Chris Brown carry her toy poodle, he also carried her shopping bags as the two did some damage to their credit cards on Melrose yesterday.

Leighton Meester

Leighton Meester returned home to New York after her trip to Los Angeles for the Teen Choice Awards with her pooch in tow. She looked a little sleepy and not thrilled to be greeted by the photogs.
