LawnMutt is an easy to apply, liquid soil amendment, for repairing dog urine spots in your lawn. Dog urine contains high levels of urea nitrogen. High concentrations of urea can damage a lawn's ability to absorb moisture. Health soil converts urea nitrogen into a more lawn friendly nitrate nitrogen that's easier for the lawn to absorb. LawnMutt repairs and enhances the soil's health enabling it to process higher levels of urea. By metabolizing the excess urea you can prevent dog urine spots in your lawn. 

Are you interested in repairing and preventing dog urine spots on your lawn? Preventing urine damage is a process that varies from lawn to lawn. Our LawnMutt Soil Amendment in combination with one-on-one support has helped thousands of customers prevent urine damage to their lawn. We would like to help you with your lawn.

LawnMutt is a liquid concentrate that is best applied with an applicator that goes on your water hose. Our LawnMutt 2 Application Pack is available with or without a reusable Hose end applicator.

Not sure the sq ft of your lawn? For reference, look at the pictures above for size comparison. The pictures above are of lawn areas approximately 800-1600 sq. ft.  If you are still unsure email me a picture and I should be able to recommend a bottle size. My email address is

The application is as easy as watering. Simply pour the contents of one 8 oz. bottle into the applicator bottle and add 24 ounces of additional water. Set the dial on the applicator to the 2 oz. setting. Apply to the lawn area evenly until the applicator is empty. Then just water for 5-10 minutes after to saturate down to the root zone. It is that easy. no additional measuring or worrying.  

Repeat the process with the second bottle 3-6 weeks later to continue the repair process.  

After the second application, you should start to see a decrease in the number and severity of new urine spots as well as the shrinking of existing dead spots. 2 applications are usually enough to start the repair processes on all but the most severely damaged lawns. These lawns can take a bit longer and a few additional applications. 

Due to the volume of urine applied to most lawns, regular applications every 3-6 weeks is recommended and prevention of new urine spots will get better with each application. 

LawnMutt is safe for people and pets when used as directed and no special safety requirements are needed.

Dead spots can be reseeded 7-14 days after application. 

To help keep your applications on a regular schedule we now offer a Subscription Service.  

 Depending on the severity of the urine damage 1-2 applications may not be enough to completely stop the new urine spots. To ensure all our new customers are satisfied with their results, check out our exclusive SoundStart Program.

I purchased the soil amendment product late fall. By then the weather changing had slowed the growth of grass. However, up until that point it appeared it was going to help with the yellowing of grass due to animal urine. I’m looking forward to spring and the opportunity to see if it will truly help to repair my lawn.

Snow disappeared last Spring and left us with a very blotchy yard after acquiring a new puppy. After Lawn Mutt we now have a spot free lawn without the use of any other fertilizer products

Fantastic product and customer service

I had extreme lawn damage caused by my three dogs. It was late summer when I did my first application. I also seeded at the first time as the application and it had no ill effect on the seed. I watered daily and did not cut the grass in between applications. Absolutely massive improvement. The seeds took hold in the dead areas and the rest of the yard grew steadily and turned a deep healthy green. The bulk of the dead spots grew new healthy grass within those three weeks. The two spots that couldn't recover from habitual urination I dug up the soil and replaced it. Then did another seeding in those areas and they did germinate. It is late in the year of Chicago weather for new seedlings to stick but we will see. I've done three applications and the difference is amazing. Jeff the owner was in contact the whole time. He gave me advice and and information I could need. We will pick back up on applications in March to recover the lawn from the winter of abuse it's going to have with the dogs, but I'm confident Lawnmutt will have my yard looking great again before summer hits. In the pictures you'll see the before middle and the end of only 6 weeks with two applications.

Highly Recommend this Great Product!

I started using LawnMutt and the Liquid Humate in August after my new pup's urine started causing awful brown spots in my back lawn. I also had noticed that the overall look of the lawn just wasn't as green as it had been even though I was watering regularly. I especially liked the fact that this was a treatment for my lawn and not something that I needed to give to my pup to change his urine. Right after my second application I felt the lawn was already looking healthier but thought it was just wishful thinking. But then, within the next few weeks, it became apparent that the entire lawn was looking greener and healthier even though I had not changed the amount I was watering. It seemed that the water was finally able to get into the soil and benefit the grass. Now that I know the products work, I might even start applying the Liquid Humate to my front lawn in the Spring as it could use some help too! Looking forward to having two healthy, green lawns!

Lawn Mutt Lawn Repair

I am the owner of a four year old female German Shepard. Her urine has killed most of my backyard and I am continually repairing it to no avail. I was hoping lawn mutt was going to be my salvation. As of September I have applied four applications and have noticed almost no difference. There are many, many, dead and dying spots. I can send photos if necessary. I am so sorry this hasn’t been effective so now I have to begin my usual reseeding and repairing of the dead spots.
