It ain't the first time the dogs been there, the deer are used to him & might slip up & get comfy and walk in after he leaves. I don't shoot a mans dog unless it poses a threat. I've been pissed watching a neighbors dogs run deer round & round like anyone, but it really ain't the dogs fault, it's the sorry assed owner. I've known a lot of smart dogs but never met one that could read a Posted sign...
