Donna, I have a signon my privacy fence that has a picture of a Rottie and says ( I can make it to the fence in 3.5 seconds can you ? )It says nothing about beware........ and I do have a no tresspassing sign....I also made my gatesopen into the yard so my dogs CAN NOT jump on them and open them up , they also have locks on them . My gates used to open out but my Rottie ( Kitty figured out how to open it and take a walk !!!! Thank goodness everyone in my town knows my Rotties and would call and say she's taking a walk about again.....LOL They no longer do that now !
