As a few have mentioned already, it depends on the dog and the owner. From my research of a few years ago, the recommendation is to allow larger breeds to go up to two years before spay/neuter for physical development. I believe @NatJ described it well in his post.
As a keeper of fur-companions, I have no interest in breeding to improve the breeds of any cat or dog I live with nor do I wish to deal with a female in estrus or a male going brain-dead at a whiff of any such female. So, they all go under the knife as soon as possible. My current cat and dog are 16 years old. Others in my past have lived between 12 and 20 years. While not proof, I don’t believe early spay/neuter causes as many health problems as it avoids.
As for “just keep the female in heat away from males” advice - good luck with that. The drive to reproduce is among the strongest for any living organism. I’ve seen/heard of more “accidental” litters than I care to think about from people using that method of pet population control.
I’m such a huge fan of the procedure that I support it 100% - by which I mean: me, too.
