User blog comment:MDGeistMD02/Horses in Dishonored/@comment-3242762-20131120104027

While there is no empirical evidence that there are horses in Dishonored, it's a pretty risk-free assumption that the T'ack and Saddle 'Emporium is something affiliated with our equestrian hoof-beating friends.

I'll rule out the idea that it was simply too difficult or time consuming to include, maybe it was, but I'll pretend it wasn't.

Maybe, if we see whale Oil as an Industrial boom, which it effectively was/is. Then horses are perhaps an out-dated commodity. For military purposes I imagine horses are extremely useful and were probably used extensively, I guess, though, that they would've been superseded by Sokolov technology, very quickly.

I'd say, they existed but the majority have now been turned into horse meat.
