"Rescuing an animal that has been terribly abused is probably one of the most heartwarming things any of us can do. But simply removing them from the situation is just the first step towards saving its life. These animals face a long road of recovery.
This difficult road consists of both a physical recovery as well as a psychological and emotional recovery. It takes these animals a bit of time to really be able to trust and be comfortable with humans again, which is totally understandable.
The hardest thing for a rescue animal is to find a home where they will be taken care of and loved forever. This especially goes for those animals that have experienced severe physical ailments or psychological problems from abuse.
