1. Dilute the urine. As soon as possible, use a hose to water down the area where your dog has urinated. This will help to dilute the urine and prevent it from burning the grass.
2. Rinse the area with a vinegar and water solution. If the urine has already burned the grass, you can rinse the area with a solution of one part vinegar to four parts water. This will help to neutralize the urine and remove any remaining stains.
3. Apply a lawn fertilizer. Fertilizing your lawn will help the grass grow thicker and more resistant to damage from dog urine.
4. Train your dog to urinate in a designated area. This is probably the most effective way to prevent brown patches on your lawn from dog wee. Choose a spot in your yard that is away from plants and trees and train your dog to urinate there. You can use positive reinforcement, such as treats or praise, to encourage your dog to use the designated area.
5. Use a dog urine repellent. There are commercial products available that can help repel dogs from urinating in certain areas. These products typically contain ingredients that dogs find unpleasant, such as pepper or citronella.
If you are concerned about the amount of dog urine on your lawn, you can have your soil tested to see if there is a problem with nitrogen levels. Nitrogen is a nutrient that is essential for grass growth, but too much nitrogen can cause the grass to become weak and susceptible to damage from dog urine. If your soil test shows that there is too much nitrogen, you can adjust your lawn care practices to reduce the amount of nitrogen applied.
