One California dog traveled more than 728 miles after being separated for days from its owner.

Bear, a 20-pound terrier vanished outside of Sacramento. Three days later, the dog was dropped off at the Humane Society's shelter in Tacoma, Wash.

No one is quite sure how the dog disappeared or how he made it to Tacoma.

"I think somebody picked him up to keep him. He had a name tag with phone numbers, my last name, and I got no phone calls. Everybody wants him that sees him," said Bryan Rapozo, the dog's owner.

"We were all upset. My wife, me, the whole family has been upset over the fact that Bear's was missing because he's such a loved animal," said Bryan's father Bret. "Once we got that phone call on Thursday, it was like the whole weight lifted off our shoulders. It was amazing."

A microchip placed underneath Bear's skin helped the Humane Society locate his owner.

"We've returned a lot of animals to their owners, but this is really spectacular," the Humane Society of Tacoma's Marguerite Richmond said.

When Bear spotted Rapozo, he ran straight to him. But he quickly became distracted by a couple of cats that were waiting to be adopted.
