Awesome product


I was a little skeptical when I first saw this product, but decided to give it a try. I have been using them for almost 5 months and there are no yellow spots in my yard anymore. In fact the grass looks great and looks like it did before the dogs. Love this product!More > < Less


update from 5/25/2015


I had initially given this product a "3" rating after using for three weeks. I was still seeing yellow spots on my lawn. It has been 6 weeks now and I am happy to say that I no longer see spots on my lawn!!

I have decided the price is fair in order to keep extra chemicals out of my dog and putting a product on her food.

Dog Rocks - Burn Patch Preventor

About Dog Rocks

Greener Grass

Since the rise of the great American suburbs, a beautiful green lawn has been the mark of stability and character. Following its establishment in North America and Europe, the lawn appeared in Australia, where a naturally occurring paramagnetic igneous rock is also found.

This igneous rock is used to make Dog Rocks, which has been helping families across UK and the rest of Europe—including most of the UK’s royal families—in keeping their lawns lush by preventing nasty yellow dog urine burn stains!

Dog Rocks are 100% natural and do not alter the pH urine balance of dogs in any way; they work by removing any nitrates and tin found naturally in water, thereby providing your dog with a cleaner, healthier source of water supply. Simply rinse the Dog Rocks, place in your dog’s water bowl and replace every two months. Soon, Sparky won’t ruin your uniform, green lawn anymore—and you’ll have admiring neighbors!
