A 200-pound dog is missing from his Florida home. There’s a reward for his return

A Florida couple's 200-pound best friend is missing and they're offering a reward for his return.

Will and Jamie O'Shea live in their Treasure Island home with Logan, their 200-pound St. Bernard, according to FOX 13.

Logan, however, has been missing since Monday, when the couple left the house for about 45 minutes only to return to find their dog gone. A backdoor was found unlocked but closed, FOX 13 reported.

Will shared Logan's picture to his Facebook page, asking anyone who has seen his dog to reach out with information. Logan's information and photo were also posted to FidoFinder.com.

The couple is offering a $500 reward for Logan's return, according to Will's Facebook post.

Will told ABC Action News he fears someone saw Logan, a 7-year-old purebred St. Bernard, and took him. They have filed a report with local police.
