A common lawn problem for pet owners is damage from dog urine. Dog urine is high in nitrogen content and can lead to dead grass and yellow patches on your lawn. While nitrogen can be a nutrient for grass, dogs tend to urinate repeatedly in the same spot and this concentration in nitrogen causes damage.
Observe your dog's elimination habits. Take note of when he urinates.
Saturate the urination spot with water within nine hours after he urinates. Use either a hose or a watering can full of water.
Soak the urine spot with approximately three times the volume of water to the amount of urine. This will spread the nitrogen throughout the lawn allowing it to fertilise rather than burn the lawn.
Use a shovel, or gardening spade, to remove the damaged piece of lawn.
Reseed, or replace the sod, with the same type of grass currently on your lawn.
Water and fertilise as recommended by the seed company.
Train your dog to urinate in one section of your lawn. This will make damage control more manageable.
All yellow spots on the lawn may not be caused by pet damage. Investigate the cause of the problem prior to assuming damage is due to your dog.
