Yes, I had always heard that, too. And we have had problems with un-neutered males, but if we spay and neuter early, everyone gets along. We have two males and two females, all adult. What we have to guard against is having the two male labs take off wandering. They are allowed to play together but only when there is a human along. Nancy
