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.

The Medium Lawn Refill Bundle is formulated for lawns 800-1600 sq ft. That would be the lawn area of a standard home on approximately 1/2 acre. 

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.

Awesome product and great service

I have a small area of grass and a large German Shepard which leads to an over powering smell of urine in the back. This product has significantly helped. There was also a little hiccup in the shipment at the fault of my own. The owner went over and beyond to assist me. Thank you again!

It’s a miracle!

I have 5 large/XLarge dogs,(Newfoundland, 2 chocolate labs, 1 golden retriever & a great dane/husky,black lab,shepard mix) and usually my yard is completely brown and horrible looking. I saw Lawn Mutt and decided to try it and it has saved my back yard. Yes I still have some brown/yellow spots but not nearly 1/4 of what i usually do. Yes I will keep using this product. I wish I would of found it years ago!

Excellent Product-Excellent Customer Service

I am so lucky I found your company and your product. As a new dog owner with brand new sod it was a recipe for disaster until I started using LawnMutt. And any time I have a question I get excellent customer service and all my questions answered. I have recommended LawnMutt to everyone in my neighborhood. My grass is lush and green thanks to this product!!!

Charlene Hammons (Bremerton, US)

I started with brand new sod and 6 weeks after I let the dogs out on it and it was ruined. I started using sound soil and I have grass coming up. I thought that I wasted my money putting down new sod. But now I have hope.
