Your companion in MGS V is a dog

In a recent trailer for Metal Gear Solid V we were introduced to DD the dog. He will be your new companion. However he is optional so if you want to keep him safe just leave him with ocelot.

When you first get DD he will be nothing more than a cute puppy. However over a few days he will be trained to become a merciless killer.

The is also good for kojima because he now has another way to break our hearts.
