He's only 3 years old....don't give up!! where there is a will, there is a way. Is there a non-profit vet somewhere (hahahha funny I know) heck you're a vet tech, splint his foot and put an elizabethan collar on him until you can find some way to take him to a vet.
I shudder to think of what would happen if my Juneau got sick or hurt.
