Is there a way to neutralize the effect of urea in dog urine on the grass, by either additives to her food or by an application to the grass?


Googling "Dog Urine Lawn" I found that the problem isn't the acidity of the urine, but it is the intensity of the nitrogen in the dog urine that causes the lawn burn. This is particularly true in female dogs. So trying to neutralize the acid with baking soda or lime or trying to reduce the acidity of the dog by reducing its dietary protein is not tackling the true source of the problem.

These suggestions on the internet seem credible and offer some procedures and products for treating the lawn:

There are certain food additives sold in the dog magazines that claim to address this problem although I have not used them. Are you sure your dog is getting enough water? The more water going through the more the urine is diluted and the less damage to the grass.

Hope this helps.
