I once had a pair that would do this every time I would play Gray Fox pup tape. Would bark the whole way in and then just stay out of range, running back and forth..Awesome..Took my brother along to hear this and a .22rifle, when male hopped up on a stump to check it out he got one to the head...Maybe if you played a distress sound and used the bark sparingly, you could stir something up..That's what experimenting is all about...what do you have to lose??
