Quote fromThis is a good idea even if the dog just follows you around and doesn't do anything.
I only hope the dog is invincible because that would be kinda uncool if a creeper killed your dog.
And maybe you could dye him any color like sheep.
Perhaps the dogs could respawn with you after you die, so that even if they die they'll come back eventually. And for everybody complaining that dogs would suck, notch could either A add an in game option to turn them off or B just ignore them. I mean honestly there isn't much to complain about here.
Minecraft is a game for creativity and inovativeness(I hope thats a word). You always have to remember that whenever you hear the word Minecraft you have to know that anything could happen. No matter what happens Minecraft will still be Minecraft and haters will still be haters.
