There are several contributing factors that increase the likelihood of developing brown spots on lawn.

• Female dogs are more likely to cause lawn burn than males because they void their entire bladder in one location instead of lifting their leg and marking, like males.

• Large dogs deposit more urine so they increase the quantity of nitrogen in one location, making lawn burn more likely.

• Those dogs, usually young active dogs, fed a high protein diet are more likely to produce a urine that causes lawn burn.

• Heavily fertilized yards are already receiving near maximum levels of nitrogen. The small amount of nitrogen in dog urine may be all that is needed to put these lawns over the edge and cause lawn burn.

• Lawns that are stressed are more susceptible to damage. Lawns that are suffering from drought, disease, or are newly sodded or seeded are more susceptible to lawn burn.
