The other day my wife called me and said Crockett, my 5 year old lab had bitten my son. He has never even raised a hair at anyone in 5 years. This is the 3rd lab i have had and i have never had one bite anyone. I asked my 7 year old what happened and he said that he saw the dog sleeping in the back yard so he walked up to him and said his name and the dog jumped up and bit him. When i looked at the bite marks i could not take the chance of this happening again so i no longer have a lab.
