Dog Rocks are a 100% Natural Australian product.
Dog Rocks filter out impurities from water such as Tin, ammonia and nitrates.
These impurities are usually through urine, and when they connect with grass it burns the grass, resulting in a dead, yellow patch on your lawn dog rock can stop the yellow patches.
When placed in a dog's water bowl they change the Nitrogen levels of a dog's urine, meaning it won't stain grass.
Simply place the contents of a single pack of Dog Rocks into 2 litres of water.
Your lawn starting to look greener and fresher and no new burn patches should appear.
The product however will not bring a dead lawn back to life.
