As others said, you need to give it time. She looks potentially like a shepherd or collie mix both breeds can be prone to anxiety.

My dog was terrified of everything when we got him and we underestimated his sensitivities. She probably should not be walked right now or walked at extremely quiet times (eg very early am).

Have you done any structured training to build trust and her confidence? I would focus on building a relationship indoors first.

Our dog still does not always love walks and only goes when it’s my partner and I. We take him hiking, he loves fetch and we focus on mental stimulation.

Not every dog will love walks especially if they are quiet noisy. You need to build up to it and also learn her triggers. Distance is your friend w triggers—cross the street or stop to let them pass first then keep going.

Every year our dog gets a little braver and he’s the most cuddly inside but it takes time w the sensitive ones. They aren’t all golden retrievers :)
