im no pro by any means, but it seems to me it would depend on the type of bark, if they sound off like the hamburgler is in your kitchen, i cant imagine that would be real inviting to the yotes, especially yunge ones. But if the wimper, whine, and maybe even yap a little, seems like it just makes things a little more natural. You are simulating the sound of a small critter being killed, and i have never seed a dog who kills anything without making any noise.
But i cold be way off, just the way i see it.
