Huh? Annoying to maintain? Leather is really easy to maintain: you just wipe it off with a damp cloth! It does help to use some leather cleaner and conditioner on it a couple times a year. But leather seats are easy to keep looking new for many years; cloth simply doesn't age well like this. Try spilling a drink on cloth and see how easy it is to clean compared to leather.
And you're complaining about damage from dogs? How do you think cloth seats are going to fare with dogs? Most people who have nice cars and dogs end up getting some kind of fancy seat covers or other dog-specific solution, as far as I can tell, so their seats don't get ruined.
I've owned leather seats in the past, properly maintenance requires more than just wiping with a damp cloth. Yes, you do have to use leather cleaner and conditioner if you want them to last a long time.
Cloth holds up much better to having drinks spilled on it than leather. The leather could potentially be permanently damaged if you don't clean it up quickly. Most cloth seats will just need paper towels. If you really don't clean it up for a long time you can steam clean cloth seats, which you cannot do with leather.
I'm wondering if maybe you've never had real leather seats and are mistaking pleather or vinyl for leather? Vinyl seats will hold up pretty well to abuse, but they are awful to sit in.
My cloth seats hold up fine to my dogs. Typically cloth seats nowadays are a lot more resistant to scratching and tearing than leather seats are.
