And review and update your dog emergency kit.
This is a good place to start
https://www.sportdog.com/hunting-training-tips/building-a-first-aid-kitI would not use H2O2 to irrigate a wound, but contact lens saline solution in a squirt bottle (and works well for debris in the lower eyelid)
H2O2 mixed with a coconut oil shampoo works pretty well for a skunk squirted dog.
Add some form of antibleeding gel, glucose gel, vet wrap and bandage scissors (cutting out burrs, cholla tubercles) in your vest, and small needle nose forceps for pulling cactus spines or quills (works a lot better than the multitool pliers, but have one on your belt also)
Get your vet records and find a vet near where you will be hunting BEFORE leaving home. You might even ask your vet to make contact with the office ahead of time.
