The newest member of the Dawson County Sheriff’s Office has four paws and a wet nose. Arthur, a one-year-old Chocolate Lab, joined the team one month ago after completing five weeks of rigorous bomb detection, tracking and article search training with his handler, Deputy Zach Totherow. “If he’s not working, he’s the biggest goofball you’re ever going to see,” said Totherow. “But the moment he goes to work it’s like flipping the switch. He’s focused on his work.” Totherow, who celebrated his one year anniversary with the Dawson County Sheriff’s Office March 13, said he’s always been interested in public safety and couldn’t wait for the day he received his canine partner.
