You have he same degree of foresight, apparently, as many (other?) pitbull owners in the country.
When people ask “Does your dog bite?” the proper answer is “Do you see teeth?”
Any dog can.
For any reason, even one totally surprising and incomprehensible to us.
It is *our* duty to prevent them from doing so.
I admit I would never trust a lab with a 3 day old baby, however.
