Well done you for giving Dottie a home
I don't have any greyhound experience, but I did adopt back in march, just wanted to say, don't be worried if she doesn't want lots of fuss to begin with, its all new to her, especially if she's spent her life in her kennel. Let her settle in, in her own time.
Our Zara is queen of the house hold now and loves her cuddles, infact shes a little madam, but she was shy and quiet and didn't really know what to do with cuddles and love in the begining!
You'll know when she gets there, don't worry, you doing the best thing in the world for her giving her a lovely forever home
