Aww I love your puppy. We have two Labradors. Miss Molly says hi!
Another thing I would add to your list, is a dog first aid kit. So things like vet wrap, doggie OTC medications, and bandages etc. I am working on finishing up our people first aid kit and will be putting kits together for our furchildren next!
That is definitely a way to level up your preparedness. For those who cannot afford a specific doggy first aid kit - get a pet first aid book and make do with human meds.
