My wife and I have three large dogs and participate in animal rescue. A few months ago we had situation where we really could have used a stretcher to move a wounded dog. So I acquired a civil defense era stretcher for future emergencies, and while it is robust the stretcher would be difficult for one person to use. In order to overcome this difficulty I decided to add wheels to one end of the stretcher so it would be easier for one person to move. However, I didn't want the wheels to be permanently installed as there are instances when it would be better have a wheel-less stretcher. Here's how I did it.
