Solutions for Urine Burns on Lawns
Drs. Foster & Smith Educational Staff

If you have a dog and a lawn then you’ve probably experienced the unsightly yellow spots caused from the urine killing the grass in your yard. These problems are more common in households with large female dogs with well-kept lawns. However, they can show up even in lawns where the weeds outnumber the grass and the neighbors sympathetically drop off “care packages” containing fertilizer and weed killer.

There are lots of old “theories” circulating about just what in the urine causes the killing off of your prized Bermuda grass. The most common of these misguided opinions is that the urine is acidic and ‘burns’ the grass. As a result, a host of home remedies have arisen including adding baking soda, tomato juice, or vitamin C to the diet. While these products rarely work once in a while, they do help but they work because they make the dog thirstier and they then drink more water and dilute the urine. The real culprit in urine burns is nitrogen.

Because dogs are carnivores and eat a high level of protein in their diet, they break the protein down and excrete it as nitrogen in the urine. The result is a killing of the grass from an overload of nitrogen. You will get the same kind of burn if you put a concentrated handful of fertilizer in one spot. These urine burns will often have a characteristic green ring around the outside edge where the urine was dilute enough to actually work as a fertilizer. This characteristic ring can also help distinguish urine burns from a grub infestation that will also create similarly looking brown spots.

There are a few things that make urine burns more prevalent:

1) Urine burns tend to be worse with female dogs because they squat and deposit their urine in one place.

2) They also are worse in large dogs because they deposit a larger quantity of urine.

3) They are worse on yards that are already fertilized regularly.

4) Grasses like bluegrass or Bermuda grass are much more sensitive to nitrogen than rye or fescue.

5) Lawns that are stressed from drought or disease, or those that are recently sodded or seeded are more susceptible to lawn burn.

6) And finally, they are always worse when your neighbor’s dog goes on your yard.

So now that we are seeing spots what do we do to get rid of them?

Home remedies that help some of the time include:

1) Diluting the urine through increasing water consumption. Adding water to the food or adding non-salted broth to the drinking water may help. Canned food has a lot more water in it but it also has its drawbacks.

2) Feeding a high quality diet may also help since the protein is more digestible and there are fewer waste products.

3) Watering the yard daily helps in some cases but it may not be enough.

4) Backing off the fertilizer on your yard may help as well.

5) Try planting some tougher species like rye or fescue.

Some Products that can help:

1) Try Lawn Guard Treats or Lawn Guard Tabs to reduce lawn burn by getting at the cause – the urea and ammonia in your dog’s waste. Contains Yucca schidigera, which helps fight lawn burn by binding ammonia in urine to prevent lawn damage. Yucca also decreases fecal odor.

2) Green-UM tablets,Treats or Spray, to neutralize the grass-killing products in your dog’s waste and prevent urine burns on your lawn. Green-UM is a nutritional supplement with amino acids, B vitamins, and vegetable substances. Green-UM’s active ingredient is Glyco Component C1 from the Yucca schidigera plant, which prevents unsightly lawn burn from dog urine. It binds or neutralizes the nitrogen compounds in the urine or feces. It is effective within one day of use, and does not affect the internal organs of the dog. Available in beef-flavored tablets or easy-to-give “cream” filled crunchy treats your pets will love. Use Spray on your lawn to spot treat and protect affected areas from lawn burn.

3) Dogonit Lawn Repair Treatment – Reverse the damaging, burning effects of dog urine on your lawn by restoring it naturally. This probiotic soil treatment uses organic enzymes with soil cleansers to flush the salts from the root zone, allowing the turf to repair itself. If the condition is caught soon enough, the burn can be prevented. Contains no harsh chemicals and is biodegradable. Dogonit can also be used on areas adjacent to driveways and streets that have been burned by road salt.

Dogonit works by loosening compacted soils, allowing air, water, and nutrients to penetrate, stimulating deeper root growth. The build-up of salts from fertilizers, herbicides, and urine overwhelm lawn areas and cause dehydration (burn spots), which appear as localized, yellow or brown patches.
