Yes, my neutered male mounts other dogs, both male and female all the time and goes absolutely crazy when he's around a female in heat or one starting to go into heat. He's also much more likely to not back down from a fight with an unneutered male, especially an adolescent male who's trying to boss him around.
I don't know when he was neutered either, I got him at sixteen months old and he's three and a half now. I actually had him ultrasounded to make sure he was fully neutered and not a cryptorchid because he doesn't act neutered. That test shows from the scar tissue that he was actually neutered early. Vets and a veterinary behaviorist told me male dogs produce testosterone their whole lives even after being neutered, so it's really useless for behavior changes. I've seen dogs at the park get more aggressive after being neutered.
My last dog was neutered at nine and a half or ten months and his whole life, even when he was quite old, occasionally he'd meet a female he'd like and they'd mount and act unneutered even if they both were neutered. So does this dog. Apparently they can still enjoy the act just not be fertile any more.
