Dog Rocks are designed to help to reduce or eliminate the burn patches caused by your dog urinating on your lawn.
They are simply put into your dogs normal water bowl, and are entirely natural. Dog Rocks will help purify the water by removing some nitrates, ammonia and harmful trace elements thus providing your dog with a cleaner source of water and lowering the amount of nitrates expelled in their urine. This in turn helps to stop brown patches on your lawn and prevent urine burn/scorch marks on grass.
Improvement in the lawn is usually seen within five weeks.
To maintain the lawn, change the rocks approximately every two months. (200gm)
