It is one of the things that we have to put up with when there are intact males and females in our kennel. At the current time, there are two girls in season and the boys are sending up a chorus of mournful howls, expressing their lust for these girls. We have Clara inside so she isn't nearly as enticing since she is out of sight but Meddle is causing a paroxysm of passion among the dogs.
Not only do the girls mount each other during heats but the boys mount each other as well. It's a nasal overload with all the pheromones wafting through the air. Almost as bad as walking through the market area on a Friday night.
Luckily, we only have to put up with the mournful noises for about a week. Then the boys quiet down and the girls, although still isolated, are not as enticing. I guess this is another reason that I have dogs instead of children.
