Missing dog, Dallas

I am house sitting for my friend at Prestonwood Country Club Condominiums off of Preston in Dallas. I decided to bring Canela during my stay. I was letting her out to pee at the grass strip next to the woods when a car passed by revving its engine multiple times. This made her very scared to which she bolted into the woods. I don’t think she got far because the forest looks very dense, but I could be wrong. She is a very very anxious little doggie. About 1 foot big, white with light brown spots, and a light pink collar. She had a bright yellow leash as well but I don’t know if it’s still on. She also has a light blue spot on her belly. Anything helps!
