My dogs' information and emergency supplies are conveniently "stashed" in a crate I purchased on sale for $10. I have stored my pets' info in handy, colorful binders for easy access (one binder for each dog). I bought clear three-hole binder envelopes so the important stuff doesn't fall out of the binders:
Additionally, I have filed training hints and other handouts in the binders.
In the crate, there are two soft and fluffy bathmats that my dogs are familiar with: they have learned to associate their personal mat with lying down quietly and being treated and praised. I have a portable water bowl, lots of poop bags, trash bags, hand wipes, antibacterial hand wash, alcohol wipes, antibacterial ointment, extra leashes and collars, and special toys. I have a small lunch cooler in which I can put water and treats. I have trained my dogs to come to me at the sound of a clicker, so I have a clicker in the crate also, as well as an extra treat bag.
I scored a portable seat/backpack at a yard sale for $1, and have stored in the crate too, this is for me however =)
Everything I need for my dogs is stored in one place and "ready to roll", whether it be to obedience lessons, the veterinarian, a pet-friendly get-together, or an emergency.
