Sarah Himmelman and Matt Idler said their 3-year-old dog Tessa is a vital part of their family.
"I cant imagine her gone," Himmelman said. Tessa works as Sarah's service dog. Himmelman said she and her boyfriend Matt are both hard of hearing and Tessa is trained to let them know when a doorbell rings or when their phone goes off.
Over the weekend Tessa went missing while they were at Folsom Lake near the Granite Bay Boat launch. Tessa was in the car while they were packing up and leaving, but moments later she vanished.
She was last spotted in the nearby woods.
"We have just been everywhere and every time we drive home we are always looking," Idler said.
