What are Dog Rocks? Dog Rocks are an exciting and proven 100% Natural Australian product that will save your lawn from those nasty burn patches that your Dog’s urine can cause. They filter out impurities from water such as tin, ammonia and nitrates. These impurities are usually passed out through urine, and when grass comes in contact with these elements it results in urine burn on grass, resulting in a dead, yellow patch on your lawn.
We've used Dog Rocks for use, and had amazing results.
But it gets worse. What happened to the nitrate that disappeared. Either it got absorbed by the DogRocks or they transformed it to something else. And that’s where we come to the second point…
nonsense | I fucking hate pseudoscience
I found their website to be a contradiction. They say the rocks work by filter out metals such as tin that are in the water, but if water isn’t going through the rocks, they aren’t filtering anything. The website he linked to about why spots occur didn’t say anything about metals at all, it said nitrogen was the cause. I would want to know what the rocks are actually adding to the water before I tried it on my dogs, but they very carefully didn’t tell you that. I wouldn’t try them without knowing more, JMO.
