The other two males are a terrier mix (large, about 65lbs) and a Saint Bernard. Our female is a Dane.

Our breeder used to have two males, but one of hers passed away last year. They were always amicable towards each other. I am wondering, if you can never keep two males in the same household, wouldn't having a show kennel be difficult? I suppose you could seperate them ALL the time, but that doesn't seem like any way to raise dogs. JMO.
