I had a similar situation happen two years ago. Had a 22-250 on my lap as well as my shotgun. After 5 minutes of calling I see a coyote screaming in towards the fox pro, it was coming in so fast that I my immediate reaction was to raise up whatever was in my hands, which was unfortunately the rifle and not the shotgun. Right as I got the gun up I noticed the other coyote at 15 yards and running just as fast. Both of the coyotes were running perpendicular to my position and I took a shot at the closer coyote and missed and then another shot at the other coyote as it was leaving and missed. The coyotes split with one heading North and the other Southeast. I went out at first light to the same spot and set up the call so that I'd be able to see the coyote before he got my wind. After about 10 minutes I noticed some deer being spooked out of the woods where one of the coyotes ran off the night before. Having learned from my mistake, the shotgun was in my hands and a coyote that looked just like the male that I had seen the night before came in and gave me a nice 10 yard shot with the Benelli. I can't say for sure if it was the same yote or not, but he looked similar and came in hot again. After seeing the deer spook and knowing the wind direction, he was definitely circling to get my wind. So in short, I had some luck going back to the same spot even after shooting twice, whether it was the same dog or not who knows, it was still luck. I'd say try it again, just make sure your setup is as good as you can make it.
