A Treasure Island couple have been searching for their 200-pound Saint Bernard since Monday.

Will and Jamie O'Shea -- doggie parents of 'Logan; -- tell FOX 13 they are in shock. They said they left their home in Treasure Island on Monday, and Logan was inside. They returned home about 45 minutes later, and he was gone. They discovered one of their back doors was closed, but unlocked.

The O'Sheas canvassed the Isle of Capri neighborhood for six hours, but there was no sign of Logan. They believe someone stole him, and a report has been filed with the Treasure Island Police Department.

"Saint Bernards are unique," Will said. "They can't be outside for too long. They can't walk very far because they weigh so much. We are just hoping social media will help get the word out. Hopefully, someone sees him and we can get him home."

The couple says Logan is a big sweetheart and a couch potato. He's friendly, so if anyone sees him, they said don't be afraid to approach him, and to contact Treasure Island Police at  (727) 547-4595.

There is now a $1,000 reward for his safe return after a FOX 13 viewer offered to match the couple's initial offer of $500.
