My brother owned a draft horse and there was nothing he liked better than pulling. If pulling teams are animal cruelty, then so is playing fetch with your retriever.
Just another anecdote, a friend of mine has sled dogs (~30 dogs, two sleds; he's fairly serious about it) and those dogs clearly love to pull. All you have to do is jingle a harness, or start loading equipment into the trailer used to haul dogs + gear and they go nuts with excitement, crowding over and trying to be first into the traces/trailer. You lay the traces out on the ground and they immediately run to their positions, with some squabbling over who gets to be where, and wait anxiously to be hooked up. The toughest part of getting going in the morning is making them wait until you're ready to go, and then they'll happily run all day long (as long as they get suitable breaks, with food and water). Those who are hurt or otherwise getting a day off are clearly dejected by not getting a chance to get into the traces.
I've known many horses who were almost as excited about their jobs... though I've also known a few who were quite lazy and didn't like to work.
