skidish dog

I just got 2yr old gyp that I just got about 2 months ago and she is skidish. She would pee every time I would grab her since she wouldn't come to me. No one else but just me. But after keeping her in the house and take her just about everywhere I go she now comes to me most of the time and doesn't pee anymore what so ever. The breeder that had her before had her on a chain all her life and never had anyone touch her (he's an old timer like Rockin said). But I'm about to start training her all the commands and see how that works. This is my first dog this way but she seems to be coming around so we will see what happens. The good part is the breeder said if she never works out he'll give me my money back or another dog.
