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.
The couple said it's a race against time to find Tessa because Himmelman is battling a genetic disease called Usher Syndrome. Individuals suffering from Usher Syndrome lose both their hearing and vision. Tessa was in the process of training to be her seeing eye dog.
"If my vision goes she will be able to help me where ever i go,"Himmelman said.
Because Tessa is so valuable Himmelman's worst fear is someone stole her.
"She is just a good animal and she would do the work you need to do. That's what we are afraid of. Someone has her," Himmelman said.
The couple said their dog is microchipped and they are hoping someone contacts them on their Facebook page using the hashtag #FindTessa or via their Craigslist ad.
They are offering a reward if she is found safe.
