My neighbor "informed" me that she will continue to have her dog use my 8/10 grassy lawn as it's urinal. My grass is consistently being killed down to the dirt. I have bought expensive "dog/rabbit" inhibitor but it does not seem to work. I also bought a "sound" machine to keep it away, but all my other neighbors complain it hurts their ears. ANY assistance will be helpful.
Short of getting a new neighbor or a fence, you will need to get rid of that dog's scent by watering your lawn and 'washing away' any urine that may be on the surface. I have 4 dogs and to keep them from my garden area, I put tobacco juice (I put cigarette butts/ashes in a can of water to furment). This will also keep insects out too, without harming your lawn. Another thing would be to spray your lawn with a mixture of citrus and water. Most dogs dislike citrus (lemon/orange). Good Luck!
