Missing Terrier Mix in Ripon - Help Needed!

Our female dog is missing. She's a terrier mix with long, blonde wiry hair. Ears that perk up and a big fluffy tail. She is timid. She escaped from her big fenced area and our fenced off property. We have not seen or heard anything. She had a cactus collar on with her name and contact info on it. You're help is so greatly appreciated.
