The dogs don't deserve a lilac bush, skunk cabbage is more like it. You should put this episode behind you - you don't see dogs, you don't hear dogs, if dogs "disappear," you surely wouldn't notice. Just sayin', you've got more important things to do. The sooner they disappear the better. Still would be nice to have a spy cam around the coop - chickens are so entertaining you just don't tire of seeing them. Electric fence would be great too, maybe with liverwurst smeared on some of the strands - do I smell singed hair, do I hear shrieks, must be some wild animal in the night. If you have the kind of electric set up NOT to pulsate, seems like the culprits would hang around as exhibit A. I am just sick and tired of hearing of all these incidents where the owner gets off scott free.
