DOGS, URINE AND LAWN BURN : Lawn burn is caused by nitrogen in dog urine. Urine contains a high level of Urea products. Urea has the highest concentration of nitrogen for all solid nitrogenous fertilizers in common use. Nitrogen waste products are the result of normal protein break down in the body and are responsible for the lawn burn. Female dogs are more likely to cause lawn burn because they empty the entire bladder in one location instead or lifting their leg and marking like males. Large dogs increase the quantity of nitrogen in one location due to large urine deposits and are more likely to cause lawn burn. The primary goal when trying to reduce urine damage to lawns is to minimize the nitrogen concentration in the urine. ABOUT THE FORMULA : Methionine is an amino acid that helps manage normal ammonia. Brewer’s yeast contains B vitamins for a light diuretic effect. The B vitamins may help to increase urination frequency and lower the nitrogen concentration. Lower nitrogen concentration may help fertilize the lawn rather than give the lawn a nitrogen burn or “dog spot.” Yucca schidigera is an herb that binds ammonia, which helps to reduce the nitrogen burn effect caused by urine. Cranberry Extract is an herb that helps to maintain urinary tract health.
