Horse damaged trees

 That's the way it is here. Not even your own animal, technically. Most ignore that part, but doing it for others, for money, would be pretty risky.

Up here the old timers used to cut poplar or aspen for the work horses to chew the bark off of.  My sisters horse like old willows, but I hear they have tylenol like effects.

Willow and aspen have ASA (aspirin) as do high bush cranberry, not Tylenol.  ;)

I think you might find they chew poplar bark because it's a natural wormer, at least thats what some old teamsters thought.
