@taskmaster , I saw a harness from Mountain Dogware advertised online that is made for incidents just like this. It's lightweight and allows you to carry your injured dog on your back (or front!). Their website is www.mountaindogware.com
@azmedic196 , it sounds like you have done a good job of preparing to take your pet camping and preparing for a possible injury. I know that people adventure with all types of pets but REI does offer a class called Wilderness First Aid Basics for Dogs. Check www.rei.com/events to see if this class is being offered near you. If not, you can reach out to your local store to see if this is something that can be offered in your market.
