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.

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!

My Lawnmutt review

I decided to use LawnMutt because we just put in new sod in the backyard this Spring and didn't want our new puppy to ruin it. LawnMutt was easy to apply and so far our grass is looking fantastic. The only downside is our naughty puppy has decided the grass is 'delicious' and he has been running around digging, chomping and carrying huge bits and clumps of grass but I guess that's a problem we have to deal with and no soil amendment can change the naughtiness of our adorable puppy😂😇🥰🐾♥️🐾

Made a huge difference!

We have applied 5 doses of LawnMutt over the course of this summer, and it has been awesome to see the grass come back! (See photo collage below. Note that the pictures are not in order, but you can figure out the order by seeing the number of brown areas decrease.) We have a border collie who has been using our front lawn as his regular urination spot for the past 4 years, and the number of brown/dead spots in the yard had been growing and growing regardless of how much we tried to water it. After applying LawnMutt, we started to see results within a month, and it has only gotten better since then. We added some grass seed midway through the summer and watered those spots daily for a while, and some of the grass grew back where there had been none. It's not completely fixed yet, but it has come a LONG way already. Jeff has been extremely responsive and helpful in checking in and giving personalized advice, as well. So glad we decided to try this!

KCs lawn

My lawn was beyond repair and Lawnmutt saved it. With the first application I saw an improvement. I have put two applications on now and the lawn is looking awesome. I still have burn spots where he pees but they go away with each application. I am very glad I found Lawnmutt
