Poor little guy!
Perhaps try Bag Balm (aka, Udder Balm). It worked for me when I was young. Not sure why. My parents used the kind that came (and still does last time I looked) in a green square tin. It's greasy--not the lotiony stuff that comes in the black-and-white-splotched tube.
You'll probably be able to find it at a farm-type store (TSC, Runnings, etc.) or at a veterinary office that treats livestock.
If the grass looks greener on the other side, maybe it's time to start watering your lawn!
