Incidentally, horses are also afraid of dead bodies, making them one of few non-human animals to recognize death. And that's why war horses were so valuable: it took a lot of training to make them not freak out in battle.

Wow! I learned plenty about horses in this topic. I never knew that tidbit about horses being afraid of dead bodies... My country is a concrete jungle, so there's not a single horse down here. except for in the zoo. Maybe. I have ridden a horse before in a trip to New Zealand. Wonderful creatures.
I actually googled about this question and on a camel fetish forum (yes! it's true!), they say that it's true that horses are generally really afraid of camels, but Arabian horses are among those that tolerate camels really well. I guess it makes sense, since they would have grown up beside camels.
I have also never seen before a camel, so I have no idea what they smell like. I guess a horse would freak out if a llama spat in it's face.
