There are many people today who have been treated poorly. They feel beaten up, mishandled, treated badly, crushed, and trampled on. When someone's been treated like that, they begin to believe that they aren't worth much. If they were, why would anyone treat them like that?
Maybe you've been betrayed, abused, abandoned, or deeply hurt by people you should have been able to trust and it's hard for you to trust anyone. You've been hurt too often. That's Gal's story, too.
Most dogs are pretty aggressive in meeting strangers by coming right up to you, maybe even on you, but not Gal. She retreats when she sees people. She cowers and she trembles because she had been severely abused by several previous owners before she came to a safe home. She has a hard time even trusting people who want to treat her right, but she's missing a lot of loving that way. Wounded, afraid to trust, and missing a lot of love - that's not just the life story of abused dogs, it's the life story of millions of people.
