Dog Rocks are a naturally occurring paramagnetic igneous rock. When placed in your dog's water bowl Dog Rocks will filter out some of the impurities that turn the grass brown:tin and nitrates. Your dog will have a cleaner source o water.
They do not alter the pH blance of your pet's urine and are safe to use with all household pets sharing water bowls.
Dog Rocks are not uniform in size and differ from pack to pack because they are entirely natural. The weight of each pack is a minimum 200g so efficiency remains conisitent.
