Interesting.

I have bred/owned dozens and dozens of superb males, but only one has ever acted like that: Duke Nukem. That is one of the reasons I got rid of Duke Nukem: when he stopped his half-brother Anthrax in a roll, he tried to hump him.

Duke was a very game dog; he never so much as committed a turn in his life; he scratched hard as hell, and he threw MULTIPLE 2-3 hour dogs as a producer. In fact no dog ever matched off Duke ever quit ... but as a performer Duke couldn't bust a grape, and his idea of "finishing" was to hump the other dog, and so I got rid of him over this.

My best dogs (Poncho, Stormbringer, Icon, Silverback, etc.) all bred a lot of bitches too ... but they never, ever tried to hump a male at any time for any reason ... and "being bred" never affected how they performed in the [] afterward. They would immediately hit another male, and with bad intentions.

I consider that a definite weakness in an animal to "change" like that. As the old man told me, "Jack, a dog needs to show me the same thing every time, or I won't trust my money on that dog."
