+1 on the diet change.

I know many people buy food according to advertising or price tag. Reading the ingredients can be a help. The cheap foods start their ingredient list with things like corn, corn meal, wheat, barley, etc. That kind of stuff is really chicken feed, filler, not dog food, and they tend to pass through undigested. Those ingredients tend to produce a lot of "airborne gifts" and large, ploppy stools, maybe not what you would want in limited survival quarters. FWIW.
