Vinegar

• 1). Pour white distilled vinegar into a watering can. You might need several bottles, depending on the size of your lawn. Dogs do not like the scent of vinegar and will avoid it.
  
  
• 2). Pour the vinegar mixture around the perimeter of your lawn. Do not directly apply the mixture to your grass or plants, because the vinegar will kill it.
  
  
• 3). Repeat the process weekly or after rainstorms.
  
  

Baking Soda and Water

• 1). Pour 1 cup of baking soda into 1 gallon of warm water. Mix the solution until the baking soda dissolves. Pour it into a watering can.
  
  
• 2). Sprinkle the baking soda and water solution in the areas of your lawn where dogs tend to urinate. Baking soda covers up the scent of dog urine.
  
  
• 3). Apply the baking soda mixture at least twice a week to keep dogs away from your lawn.
  
  

Commercial Dog Repellents

• 2). Follow the directions on the package for lawn application.
  
  
• 3). Repeat the application every three months or as directed on the product packaging.
