Time waits for no one, but dogs certainly do!

Nine-month-old Rambo patiently waited for his owner for two days at a Hannibal, Mo., rest stop after being accidentally left behind.

Truck driver Michael Siau was journeying to North Dakota with his furry buddy, and managed to get to Cedar Rapids, Iowa, before he realized the Yorkie was gone. Knowing that the Missouri rest stop was the only place Rambo could have escaped, he contacted the town's animal control in hopes of being reunited with his puppy.

"I was in tears, sobbing," Siau told the Hannibal Courier-Post about his attempts to get help finding his dog.

Animal control officer Tim Ledbetter went to the rest stop, witnessed a family trying to take Rambo, but intervened just in time.

Following the completion of his work trip, Siau hitched a ride with a delivery truck back to Hannibal, and was reunited with his canine companion on Wednesday.
