I've had the same problem at times, but I'm convinced that something will work. What I mean is, they get hungry even when it's warm or blowing, and when they get hungry they look for food. I just don't think we're sending the message they are ready to respond to.
Last weekend I had a similar problem, so I changed my tactic. No more distress calling. I instead went to a rodent call, and just peeped it around; no terror, no pain, just "mousing around." Seven minutes into the call a big dog came trotting out of the draw, headed to the downwind side.
On another stand, I did my best to imitate a bird, but again, without the frantic cries. Just a noisy bird hanging around a juniper. Two dogs came in on that one.
Now before you dump your distress calls, realize that these results were anything but scientific, and I wouldn't want to bet the farm I could reproduce them. But I did change my tactic, and I did call in some dogs from an otherwise empty weekend.
I think I'll try it again. /ubbthreads/images/graemlins/smile.gif
