What is Causing The Dog Urine Spot Damage in a Lawn?

Dog Spots are caused by an overdose of ammonia nitrogen in by the urine of the dog. The ammonia in the dog urine causes a nitrogen burn in the grass. The center of the dog spot is exposed to too much nitrogen, therefore, burning the grass. The edges are exposed to large quantities of nitrogen, turning the grass dark green.

What Products Can Be Applied to Stop Dog Urine Damage?

There is no recommended product to prevent dog spots from occurring, but some homeowners said they saw effective results from changing dog food manufacturers, supplements of herbal vitamins, and training the dog to go to the bathroom in a different location.

The Most Effective Way to Stop Dog Urine Spots in a Lawn!

The most effective way to stop dog spots from occurring are to promote very deep digging grass roots. The deeper and more established the grass roots are in the soil the better the grass can fight off a nitrogen burn. The best method in promoting deep digging roots is to water the lawn deeply and infrequently, aerate the lawn spring and fall, mow the grass tall, and use organic fertilizers instead of chemical fertilizers.

Many Organo-Lawn customers in Boulder and Fort Collins areas have had great success by following the 1,2,3,2,1 lawn watering recommendations, which was invented by Organo-Lawn to promote deep digging grass roots.

FAQ - Dog Urine Spots

Why does my dog's urine kill the grass?

  • It is a common misconception that "acid" in a dog's urine is what causes the brown spots left behind on our lawns. However, the culprit is actually the high nitrogen content of the urine. Nitrogen is “the waste” in the urine and is the result of protein breakdown through normal body processes.

How to stop my dogs from killing the grass?

  • Dog spots in a lawn are caused by a nitrogen burn of the dog urine. The best way to prevent a nitrogen burn in a lawn is to have very deep digging grass roots. The deeper the grass roots are in the soil the more difficult it is to burn the lawn. We suggest using the 1, 2, 3, 2, 1 lawn watering technique to help reduce the effects of dog urine on grass.
