<human>: Can you summarize the given text in a few sentences?

I adopted a gorgeous one year old female Wolfhound X Australian Cattle Dog from a rescue yesterday, she was roughly abused in her previous home which has lead her to be extremely timid and distrusting of people (no aggressive signs thankfully) and very small considering her breed (smaller end of cattle dog).

The rescue was not able to get her a foster home and only had her at the kennel a week or two so they have very little insight into her nature and personality, So i was wondering if you kind folks had any advice to assist her.

When I went to pick her up yesterday she was very timid and ran away and hid under a car, i had to carry her to our car to take her home, on the trip home she mostly slept (and farted). which was to be expected, being home she still shies away from us and cowers if we're near, we're okay with this taking a long time and already in one day she has made leaps and bounds of progress. she come to us with a lot of coaxing and time, but it's progress and will take time.

The main thing i am worried about is even though she is feeling comfortable with us to an extent already, walking into rooms with us and sleeping. I am having trouble telling if she actually likes petting, she wags her tail when we're near but stops when we pat her, then resumes wagging if we stop.

She also looks away, yawns and licks our hand during petting, she also doesn't make much of a move to engage the petting again.

I've heard this are typical signs that the dog isn't happy or enjoy themselves. which is understandable given her first year of life, but i'm wondering if we should keep petting her in hopes she'll realize in time we wont hurt her, or if it's better for her not to have that stress?
<bot>: My new rescue dog was abused in her previous home and doesn't seem to like petting, should we keep showing her love, or would it be better for her to remove this source of stress?
