No more urine burn patches on your lawn! *High concentration of nitrogen in your dog's urine burns grass, leaving yellow patches. *Dog Rocks are a paramagnetic igneous rock. When immersed in water, the paramagnetism creates a magnetic field within the water, causing a change in the ion exchange, diminishing the nitrates that are found in the water. Your dog then absorbs less nitrates into his system and therefore less nitrates are present in his urine.
