Dog Spot Disease

I have been asked by many homeowners who also own dogs ,especially large dogs, what they can do to eliminate the patches of brown in their lawns. Unfortunately, my answer is always, "not much". Dog Spot Disease is created by the concentration of salts (NO3) in a canine's urine. Unless the salts are immediately pushed through the soil by applying water to the area, the effect is a dead spot. The bigger the dog, the bigger the spot.

Here is an article that discusses a few possible remedy's.
