Yes, I have a dog/human one that lives in the car, as my car is wherever I am, basically.
I have:
- vet wrap, three rolls
- different sizes of gauze
- box of varied sizes of bandaids
- hydrogen peroxide
- pedialyte
- saline eye wash
- saline wound flush
- q tips
- miracle dust
- scissors
- tweezers
- a few different sized syringes
- liquid band-aid
- a few cans of dog/cat food (in case I need to lure a stray)
- two extra leashes
- alcohol wipes
- buffered aspirin
- benedryl
I *think* thats it. It's all I can remember at the moment, anyhoo.
One thing I did was store it all in a soft sided cooler, so that the insides don't get too hot/cold depending on the season.
Wanted to add, I also keep bowls and bottles of water in the car at all times.
