My Lab, Sadie, is really shy around strangers!! Ithink she was the runt of the litter, because she is kinda small for an adault Labrador!! Sadie is also VERY protective of our house and my family. Most dogs hate the mail man, but the mail man is one of Sadie's best friends!! She tries to go with him!!! I think Labs are ore one of the nicest and friendliest dogs in the world!! (not forgetting Goldens!!)
