Cool dogs but prepare yourself.  You also should find out if it has been socialized with other dogs?  My son had an Ole English Bulldog that he had to give away after seven years of loving her because of a job change and move.  We couldn't take her because she never got along with our Aussie or Catahoula who both love other dogs.  My neighbor across the street has an English and it is very unsocial with other dogs.

The world is full of people bitten by "not a problem dog."
