Rachel Bilson took her pet dog for a walk in the great outdoors. Bilson went to Grifith park in Los Feliz on Wed., Oct. 29. Her dog is named Thurmen Murmen. He has a surname, just like a human and I am surprised his surname isn’t Bilson. Thurmen Murmen met some of his fellow canines and enjoyed a dog chat with them. On the way back to the car, Thurmen Murmen threw a fit so poor Bilson had to carry him.
