Everyone knows that dogs are a man's best friend, but Sidney, a 5-year-old black Labrador, is more than that. And now he's missing.
Sidney is Caroline Mosely's trained guide dog. Mosely is legally blind.
"We're trained to pay attention to him, and he's trained to pay attention to me," Mosely said. "He's trained to show me the steps. He's trained to stop at every entry doorway, so he lets me know I'm at a door."
Sidney leads Mosely to work every day and also travels with her on trips.
"He goes everywhere -- even airplanes, buses, trains, grocery stores, everything," she said.
Sidney disappeared from his Southeast Dallas backyard on Wednesday after being spooked by fireworks.
Moseley took Sidney's work harness off on Wednesday evening. To the dog, it means work is over and it's time for play. When she let him out in the backyard, she heard neighbors popping some fireworks.
When she opened the door to call Sidney in a few minutes later, he was gone.
"I get up, even now, and keep looking like, 'Can I go get him?' Or, 'I got to go feed him,' or, 'What is he doing?'" Mosely said. "Without him, it's just like something's missing. He's like my best friend. I look down for him every time, keep looking for him every time."
Mosely has checked the Dallas animal shelters, but no luck.
Sidney is a black lab with a white patch of fur on his chest and some white fur under his chin. The inside of his ears are tattooed with the code 449P.
The Moselys live near the intersection of Jim Miller Road and Forney Road. Anyone who might have seen Sidney can contact the Guide Dogs for the Blind at 1-800-295-4050, extension 4090.
Sidney was trained by the group Guide Dogs for the Blind. A local club, the Lone Star Guide Dog Raisers Club, plans to help Mosely find the dog in the neighborhood by posting signs and going door to door starting 11 a.m. Saturday.
