I heard they wanted to allow dogs to run free at a lake somewhere, to chase off all the geese that otherwise wander the banks endlessly pooping and messing up the grass.
The big problem of course was that the dogs ended up pooping also. When meant a progression of ever bigger and badder animals, bobcats to chase away the dogs, wolves to chase away the bobcats, wild boars to chase away the wolves, tigers to chase away the wild boars, lions to chase away the tigers, etc. Because they're all pooping on the grass.
Just put up a fence or kill the geese.
