Terrified lost dog (Marysville)

We adopted and adult female golden retriever last Sunday Feb 11.
Her lead broke at the beginning of the Bayview trail on Getchell at 9:10 on Saturday Feb 17th.
Our home is nearby on 83rd.
She lived in a barn as a baby mama for the last 3 years, and she's not trusting of humans.
We've only had her one week, and she is very skittish and terrified of cars and any noise.
She is 70 lbs, and was last seen wearing a light purple harness with her broken black lead trailing behind her.
Someone posted on the Snohomish County lost dog site that they saw her running with the broken lead trailing behind near Cedarcrest golf course.
Yesterday we looked for her on foot but didn't even catch a glimpse of her.
(Thank you to all the kind strangers that helped me look for her.
) Any information or sightings will help, please text me at show contact info , thank you.
Her name is Daisy, but that was the name she was given by the previous owners and we kept it.
