I also don't have enough experience with reptiles to say as the only reptiles I've had, aside from bluebellies, the sex was unkown.

In regards to dogs, however, I would just like to add that what people interpret as "protective" behavior is often territorial, dominance, resource guarding, food aggression, etc. A vast majority ( I'm talking like 99% ) of dogs will not "protect" their owner in the face of a true adversary, with real pain and a real confrontation. Very specific genes and training/conditioning go into the training of a dog that can handle the mental and physical stress of combat with a human.

Females are often noted to be more aggressive as females fight amongst themselves more and spaying a female dog increases aggression among many other health risks and that neutering a male dog unless done very young *which is TOO young* does not affect aggressive tendencies and even when neutered young males are capable of being aggressive, to people, to dogs, to other animals.

In mammals and most other species that live with humans, it is not the sex that determines aggression levels it is the handling and training of those animals that determines outward aggression. Yes animals are born with certain traits that make them more or less inclined towards aggression - namely dominance - but these inclinations can be suppressed, redirected, and prevented even in animals that are already showing strong, dangerous, aggressive tendencies.

I've worked with dangerous animals most of my life. Aggressive dogs, horses, cats, birds, ferrets etc and while not easy aggressive tendencies can be worked through. That said I do believe this poll is directed towards reptiles, which I don't have enough experience with to vote. I will say that I think it would be more of an individual thing, not directly linked to sex.

Just my 27 cents lol
