Help Find Foxy: Lost Tan & White Chihuahua

My furbaby is a female chihuahua and her name is Foxy. She is a rescue, she is best friends with my other chihuahua and missing puzzle to our little family. She is Tan with white fur on her neck down to her front legs and paws. She is really sweet and friendly. She got out from our sliding door that opened somehow and went through the bottom of our gate. We miss her so much, please help me to find our beautiful Foxy. Thank you in advance for any of your efforts.
