I use dogs for rabbit hunting, they do a great job of chasing the bunnies.
I have used dogs twice to help recover a deer that we lost the blood trail on, but the dogs have to be trained to do that, my rabbit hounds won't work.
I have duck hunted with dogs too, but they just retrieve, and that is something the hunter can do on his own.
So, I guess dogs can be useful in a survival situation too.
