I think adding dogs to the game would be awesome. You give them food, they love you and follow you around. Maybe they help you find loot or bark when zombies are around. Or you could train them to be quiet if you are the stealthy type. It would take a bunch of coding and design, but I think it would add a lot of value to the game. If another player shot my dog, I would go to war. If my dog was bitten and became a zombie dog and I had to shoot him, I would cry. (That is straight out of I Am Legend)
