Yes, there is implied liability in NV.... therefore signs must never say: caution, warning or imply that there are dangerous anumals on the property. My insurance agent specifically requested that I use only signs that state fact. I have two that say "Dogs on Premesis", also have some like Brenda's that state:"WARNING LIVESTOCK GUARDIAN DOGS WORKING DO NOT DISTURB"... beyond that there should be no signage that implys viciousness or probability of an attack or biting.......
