I’ve had two male dogs, an old English sheepdog and a little rat terrier/chihuahua mutt, neither were neutered, no problems, both lived 13+ years.
One of my present mutts, an adopted stray, still has his set. Two years now and no problems with him either. He does try to hump every dog of either persuasion that will hold still long enough in the dog park but hey, what happens in the dog park stays in the dog park.
We don’t go to those places much anyway.
