Article Overview

Why Does Dog Pee Kill Grass?

Dog urine has high concentrations of nitrogen. Some nitrogen is healthy for your lawn — in fact, many lawn fertilizers contain low concentrations of nitrogen. But too much nitrogen essentially burns the grass.

Female dogs can cause more damage because they typically squat in one spot, while male dogs mark their territory in multiple areas and around trees, bushes and other upright objects.

5 Tips To Prevent Dog Urine From Killing Grass

There are several things you can try to prevent those unsightly brown spots from forming.

1. Use A Leash

Taking your dog out to pee on a leash gives you control. This way, you can keep her from urinating in the same spot every time.

2. Train In A Designated Area

You might want to consider creating a pile of gravel as the pee spot or choose an area of the lawn that’s not so visible. You could also put a pee post in your yard, like the Lulind Dog Fire Hydrant Garden Statue or the Simple Solution Pee Post that’s infused with pheromones to attract your dog.

3. Encourage Your Dog To Drink More Water

Drinking more water helps to reduce the concentration of nitrogen in urine. It’s also healthier for your dog.

4. Use A Dietary Supplement

These supplements include natural ingredients like cranberry, probiotics and apple cider vinegar to keep your dog’s digestive system healthy and reduce the amount of nitrogen in your dog’s urine.

Caution: Most of these supplements contain DL-Methionine to neutralize the urine. This ingredient can be harmful to dogs with pre-existing liver and kidney disease.

5. Spray Water On The Area

Although not as practical, you can also spray water on the area right after your dog pees. This can help dilute the higher concentration of nitrogen on the grass.

Personal Experience

Michelle S., the co-founder of Canine Journal, was able to control the smell her dog was causing outside. Read about her experience below.

Our dog Barley has the WORST smelling pee of any dog we have ever had! Our yard was starting to smell pretty bad, quickly. The only things I could find online were to water the yard more to dilute and wash it away and to add lava rocks to the dog water. Most other options are not natural and less appealing…plus they don’t get the best reviews.

But we found PetHonesty Green Grass chews which includes probiotics, and it has worked great! We have been using it for four months now and we no longer have a smelly yard plus our grass is staying green and healthy.

Home Remedies

If you prefer, you can try a homemade yard odor eliminator.

  • For grass, sprinkle garden lime on the area. This helps both to eliminate the odor and neutralize the urine to help restore your grass.
  • For grass, use an oscillating sprinkler daily on the affected areas. The water will slowly dilute the urine, so it seeps into the soil.
  • For non-grassy surfaces, sprinkle baking soda on the area. Let it sit for an hour, so it absorbs the urine smell. For cement areas, use a scrubbing brush to scrub the area before letting it sit. Rinse with fresh water.
  • If the urine has dried on a porous surface, like cement, mix bleach with water and pour it over the surface. Allow it to sit for 10 minutes before hosing off the area.
