Well, it looks like you'll just have to get within 25 yards of your quary.
I know all about dog problems. We've had a couple running on our lease every morning and afternoon this season that are causing us fits. You can be watching a couple of does on a food plot, waiting for a buck to step out. If someone shoots on the next plot over those does don't even lift their heads. But let those dogs start driving anywhere on the lease and the deer vacate the plot.
My brother-in-law caught a picture of them on his game camera. We've named them "Target 1" and "Target 2".
