What happened to the dog in Gladiator?

I'm currently watching Gladiator (about halfway done), and I noticed that after the first battle scene, the dog is not mentioned or seen again. Does he come up in the end, and if not, what was the significance of having it?|||nothing happened to the dog. It just wasn't a relevant part of the story. at all. Like what happened to a particular soldier on the front corner of the third group. What happened to the bird in the very beginning. What happened to all the horses. hate to spoil it, but the dog does not have any future part in the movie, and was of no real interest to the whole movie, but to show that dogs were used in battle as well.|||the king killed the dog.
