A Grammy-winning recording artist is contributing to a Long Beach woman’s $10,000 reward for the return of her missing pit bull, named Moqui.

“I saw it on Instagram, and I thought ‘Oh my gosh, this is so painful,” singer Duffy said in a telephone interview.

Duffy, who called from London, has also posted a picture of the missing dog on her Instagram account, @iamduffyinstagrams, with the words “missing” and “#findmoqui.” Several images of Moqui have been shared on Instagram, and Duffy said she learned of the dog’s plight after a friend tagged her in a message.

“I was in disbelief that someone from the UK heard about it and felt so touched by it,” said Moqui’s owner, Monique Hayward of Long Beach.

Hayward said her dog was stolen from her about noon Feb. 22 from her car while she was parked near a Cambodian restaurant on 15th Street near Cherry Avenue. A report is on file with the Long Beach Police Department.

“I left her in my car to grab some food for about 20 minutes. When I came back, she was gone,” Hayward said.

Hayward said there was no damage to the car, and that Moqui could not have wriggled her own way out of the car through a crack in the windows.

Moqui is 5 years old with a brown and white coat. The pit bull has white fur covering her chest, paws and the tip of her tail as well as an eight-inch surgical scar on her belly.

Hayward has experienced a great deal of stress since the theft, she said.

“I am so sick now because I’m stressing out. I feel like a mess. It’s really hard,” Hayward said prior to being contacted by Duffy. “I don’t know what to do with myself.”

Duffy said she decided to contact Hayward after learning of the dog’s loss. She has not previously pledged financial support for such a reward effort.

“It can ruin your life,” she said. “I just really feel for her.”

The singer said she did not want it to be known how much of the reward would be financed by her pledge.

“We really want Long Beach to get behind this,” she said. “We need the power of the community to find Moqui.”

Duffy won the Grammy for Best Pop Vocal Album for her 2008 release, “Rockferry.”

Long Beach police confirmed they took a report of the case. Anyone who may have information on the dog’s theft is asked to call the police department’s burglary detail at 562-570-7351.
