Dog Rocks are a 100% natural prevention & cure to the burn marks that appear on grass after your dog urinates on the grass.
You simply place the rocks in your pet's drinking water and they work like a sponge absorbing excess nitrates and other trace elements from your dog's water. This means there is less of a concentration of nitrate in your pet's urine which ultimately means that the pee will not kill your grass. Less nitrates in, less nitrates out!
One pack of Dog Rocks will last you two months and you will need to change the rocks every two months as they will become saturated by this point and will be less effective.
You will need one pack of Dog Rocks per water bowl and it is very important to make sure that your pet drinks mostly from this source of water, as any other water that they drink will not have been filtered by Dog Rocks and will therefore reduce the benefit of Dog Rocks.
There are usually 2 or 3 rocks per pack of Dog Rocks, there will always be minimum 0.44lb or 200g worth of product but as they are entirely natural the size and shapes of the rocks do vary. All the rocks from one pack need to be added to one water bowl.
None, apart from a perfect lawn or back yard. Dog Rocks have absolutely no harmful side effects to dogs, and even if your dog shares his bowl with your cat's it is fine for your cat to drink water with Dog Rocks in. There is no change to the pH balance of your pet's urine.
