I'm on my 3rd lab. One expired. One stolen. My current pooch is a 5yr old female. She is the smartest, sweetest, most loyal dog I have been around.
Try again. When you find the right one it will quickly become a loving member of the family.
I ran across that show Amy mentioned. What Ceaser does with dogs is incredible.
btw - when I meet a dog for the first time I try to pet them from ground up to under chin instead of hand coming down on top of their head. If they can follow your hand they may not think you are going to hit them. Some unfortunately have been abused.
