The differences between male and female dogs are vast. People don't understand that female dogs can be just as guarding in terms of their behavior. I think they're more affectionate often and I think they're easier to train. That's not to negate the male dog. We love the boys, but I really highly recommend that you neuter them so that you don't have the issues that are involved with males like marking, roaming and fighting. If you neuter the male dog early, they're going to be just as good as females.
