I have a dog. My family knows about the dog, there's a sign for firefighters to save the dog in case of fire. That sort of covers the "if I'm not there to help" plan. I also keep an extra 35 lbs bag of dog food in the basement, when that one gets used, I replace it, so I always have extra dog food on hand. The dog is micro-chipped. In the car she also wears a collar. I keep basic pet first aid stuff (vet wrap mostly) on hand. That's about all I do. The real issue could be if we had to evacuate where we would likely not be allowed to take the dog into a shelter, so I have a few ideas of where we'd go depending on the circumstances / lead time.
