What's a good covering/coating for wooden floor boards when one has a hoard of dogs playing on it every day?

We tried the 'hard as diamond' stuff... The second attempt is in serious need of redoing, but at that price I'm loath to do it again just for it to get scratched off again in short order

We did put down new carpets once - they lasted two weeks before we had to pull the whole lot up The dogs decided there was something about the smell of it and wee'd like it was going out of fashion!

It's an Edwardian house with a lot of its period features still in place, so would like something that fits. I thought of sanding off the remaining stain and then waxing, only I'm not sure how dog resistant wax would be.

So folks Any and all suggestions please (preferably not D's of having no dogs! He's joking, I think lol).
