A dog in bed might be a nuisance to some. For Ruchir Patel, a 31-year-old Marine Corps veteran from Murrieta, when a 3-year-old Labrador retriever named Zeppelin hops into bed, it means his new best friend is on duty.
"He'll wake me up in the middle of the night if I'm having a nightmare," said Patel, who has been diagnosed with post-traumatic stress disorder.
