In many breeds, the standard was written with the male in mind. The rottweiler is no exception. So when the judge has the mental perfect picture of a rottweiler, it is of a male. Hence, the bitch doesn't often get BOB. In my completely unscientific opinion I would say that bitches get BOB about 20% of the time.
Then the bitch has to beat the rest of the working group to get into the running for BIS and again, beat the other groups to go BIS. Just getting BOB is hard for a good bitch and then getting a group one for a rottweiler, much less a bitch is that much harder.
I have a friend who has GSD. Her girl took BOB and in the group ring the judge was searching around for the testicles. My friend had to inform the judge that the dog was in fact a bitch. I have seen this bitch and she is NOT doggy at all. The group judge was just assuming that what would make it into the group ring would be a dog, not a bitch. BTW, the group judge is also a GSD breeder too.
