I don't think that a LITTLE dry dog food would hurt you, but I wouldn't make it a habit. Have you had the urge to chase cars or hike your leg in the bathroom? Have your friends taken offense to the way you say "hello"? <img src="images/graemlins/wink.gif" alt="" />

I know you were asking about eating dogfood in a survival situation, but I would be very careful about eating canned or packaged dog food unless you absolutely have to. The meat often comes from cattle that for one reason or another are not considered fit for human consumption. They often get the designation DDD (dead, diseased, or dying). That should tell you something.

You might be better off either carrying an extra canteen or two, and/or carrying some real food or emergency rations such as Mainstay or Datrex. You might also want to have (or be able to make) some means to catch or kill your own food.
