Dog Rocks

Dog Rocks® filter out impurities from water such as tin, ammonia and nitrates. One pack of Dog Rocks in your dog’s water bowl will keep your lawn lush and free from urine burn patches for up to 2 months.
Unlike many products claiming to cure burn patches, Dog Rocks DOES NOT alter the pH of your dog’s urine, it works by removing the excess of nitrates found in drinking water, making them 100% safe for dogs to use their entire lives. They actually end up drinking a cleaner source of water.
A product of Australia, Dog Rocks are pet parent and vet endorsed worldwide.
