I will probably get some flame for this but I'm going to say it anyway. It's important for people with small children to think of bug out, shelter and other similar situations realistically. I really like my dog but if comes down to abandoning the dog to do what's best for my two year old son, then, well, good luck dog, you're on your own. I would not hesitate or second guess that decision. When it comes to my little boy's safety it's an easy decision. Just my opinion of course.
