"SueNH I never heard of it being bad either.
I actually will use it to remove pine sap from my horses coat. Cheap oily peanut butter worked into the sap and then the horse will lick it until removed. Horse and peanut butter do the work for you."
Roh-oh! Now we have to ask if pine sap is good for horses.
Dogs love peanut butter. You stuff the goo into those Kong things to keep them entertained. I can't imagine a horse having access to enough PB to do harm unless they get loose in a Skippy factory.
But it never hurts to ask the question.
