Dog Rocks 200g

Dog rocks are a paramagnetic igneous rock – 100% natural rock.
Nitrates are chemicals in the dogs urine that burns the grass.
When this rock is immersed in water, the paramagnetism created a magnetic filed within the water causing a change in the ion exchange. THis in turn diminishes the nitrates that are in the water so that when the dog drinks the water, less nitrates are being absorbed into the system and therefore less are coming out in the urine.
