I have only owned one male dog, so I
really can not compare.
My whole family prefers females.
When I got my male they all got up
in arms about it. lol
Now that I have him everyone loves him.
I still prefer females because
they are smaller and I like their (plumbing better) lol
I taught my male as a puppy, that leg hugging
on humans and other dogs is not acceptable behavior.
Other than that I have not noticed
much of a difference, and all my dogs are spayed.
