We have lists for everyone in the household and yet we often neglect the four legged family members or just flat out don't know what to prep. Great instructable going over dog preps. Covers the basics and there is room to add. I would throw in a tick remover tool to the kit for starters. Besides being a bug out bag for Fido, I think this would make a good hiking kit too.
