Dog Rocks are the original Australian answer to the yellow burn patches your dog leaves on the lawn. They are not a supplement and nothing is given to your dog — you rinse the rocks, drop them into the water bowl, and they work on the drinking water itself. PeekAPaw stocks the 200g pack for a single bowl and the 600g bag, which holds three 200g measures. If you have been looking for a way to stop dog urine killing the grass without changing your dog's diet or dosing them with anything, this is about as low-effort as it gets: no tablets, no powders, no retraining, just rocks sitting in your dog's water bowl that get swapped out every couple of months. How Dog Rocks work Dog Rocks are a naturally occurring paramagnetic igneous rock, mined in Australia. Placed in the bowl, they help draw impurities such as nitrates, ammonia and tin out of the drinking water. It is the nitrate concentration in dog urine that scorches grass, so lowering the nitrate load in the water lowers it in the urine — which is why the rocks go in the bowl rather than on the lawn. How to use them Rinse the rocks under a tap before first use. Use 200g of rocks per 2 litres of water in the bowl. Make sure it is the only water your dog drinks — a second untreated bowl, a pond or a pool will undo the effect. Replace the rocks every two months. Spent rocks cannot be washed and reused. Natural and safe for dogs and all other pets, and fine to use alongside any diet. Which size to buy The 200g pack treats one 2-litre bowl for about two months. The 600g bag is the same rock in a larger quantity — three 200g measures, so roughly six months of cover for a single-dog household, or about two months for a home running three bowls. Once you know Dog Rocks work for your dog, the 600g bag is the size that saves you re-ordering every eight weeks. What to expect Give them a couple of days to a week to take effect, since the change comes through the water rather than the lawn. Dog Rocks prevent new patches; they do not repair the ones already burnt. Reseed or re-turf the damaged spots and let the rocks handle what comes next. Results also vary with your water supply — households on tank or rainwater sometimes notice less difference, because nitrate levels were low to begin with.
