Dog Rocks Urine Patch Preventer 600g Bulk Bag Clear

Dog Rocks are 100% natural Australian basalt stones designed to reduce lawn burn patches caused by dog urine. You simply place them in your dog’s water bowl, and they help filter out impurities like tin, ammonia, and nitrates, which are the culprits behind those yellow spots on your grass . ✅ Key Benefits Natural filtration – removes compounds that cause urine burn Safe for dogs – no additives, chemicals, or side effects Easy to use – rinse and drop into your dog’s water bowl Lasts ~2 months – one pack treats up to 2 litres of water Works with most diets – especially effective with kibble-fed dogs ⚠️ Watch Outs Not a miracle fix – results vary depending on water hardness and dog size Requires consistent use – top up water daily, replace rocks every 2 months No scientific proof – vets say anecdotal success, but no clinical trials

I’ve been using these Dog Rocks in my dog’s water bowl for a couple of weeks now. Initially, my dog was reluctant to drink from the bowl—but she’s gotten used to it now, so full marks for safety: two medium-sized rocks per bag, meaning no risk of accidental swallowing. So far, there’s been no noticeable impact on the lawn. While it’s only been a short period, I’m optimistic—others have seen improvements in 2–3 weeks . I’ll continue to monitor whether urine burn spots appear or disappear over the next month. ✅ Pros: Safe and natural, no side effects on dog or grass. No swallowing risk—rocks are sizeable. Easy to use—just drop into drinking water. ⚠️ Cons: Took a little time for the dog to adjust to drinking from the treated water. Too early to call effectiveness—no visible lawn benefit yet. Overall I like them. If lawn burn becomes noticeable in the coming weeks, I may update with how effective they’ve been long‑term—but fingers crossed!

Dog Rocks – Urine Patch Preventer has genuinely made a noticeable difference to our lawn. After placing the rocks in the dog’s water bowl as instructed, the yellow patches on the grass were significantly reduced within a few weeks. I like how natural and easy this solution is—no chemicals, no changes to the dog’s diet, and no hassle. Our dog drank the water as normal, and there were no issues at all. It’s a simple “set and forget” product that just quietly does its job. The rocks last a long time and are great value for money compared to constantly repairing or reseeding the lawn. If you’re tired of unsightly burn marks on your grass, this is a very effective and stress-free solution. Highly recommended!

I bought these with high hopes, but unfortunately I couldn’t get them working as expected, so I can’t really say whether they’re good or not. I followed the instructions and tried setting them up multiple times, but they just wouldn’t work properly for me. I’m sure they might be fine for others, but in my case I couldn’t get them to function in a way that let me actually test them properly. Because of that, my review is more inconclusive than negative — I can’t comment on performance or reliability as I never got to the point where they worked. It’s disappointing, as I genuinely wanted to give them a fair try. If you’re more tech-savvy or already familiar with this kind of product you might have better luck than I did, but based on my experience I wasn’t able to use them at all.

Short review - Don't waste your money, it doesn't work. Long review - I'm a vet, and against my better judgment I was persuaded to try these as a solution to the brown, dead patches developing on our lawn. They haven't worked, and if you read the pseudo-scientific bunkum on the manufacturer's website, they were never going to. The simple facts of the matter can be summed up as follows - 1) dogs are carnivores, 2) carnivores eat meat, 3) meat contains protein, 4) digesting protein creates nitrogenous waste, 5) carnivore urine contains high levels of nitrogen, 6) small amounts of nitrogen act as a fertiliser, high levels of nitrogen act as a weedkiller (as far as grass is concerned). It doesn't matter what nonsense the manufacturers spout about rebalancing nutrients or ions in the water (meaningless), or even worse "changing the paramagnetic balance of the water" (total gibberish), you can't deny the biology. In fact, if you read carefully, they actually acknowledge this by suggesting that if your results aren't great, avoid feeding a red-meat based diet... What I will say in defence of Dog Rocks is that they are probably harmless. Some other products, whose manufacturers have even less of a grasp of biology, try to manipulate the pH of the dog's urine (in the mistaken belief that "acid" causes the brown patches), which may have harmful effects such as causing the development of kidney stones. Avoid these treatments at all costs, seriously. I don't think Dog Rocks will do this, because I don't think Dog Rocks will do anything at all. Where these things SEEM to have worked for people, it is either because they have wet lawns where the nitrogenous urine gets diluted quickly, or they have extremely well rooted grass that can cope with the excess nitrogen, or their dogs are on a low-protein diet / drinking a lot of water / or for other reasons not producing nitrogen-rich urine. It is nothing to do with these INERT rocks that do NOTHING. The ONLY truly effective solution to brown patches on your lawn is to pour a bucket of water on the exact spot that your dog has just had a wee, as soon as they have done it. If that's not practical, then your next best solution is to save the money you would be spending on Dog Rocks every two months, and buy 2 rolls of turf. Cut out the dead patches on your lawn, and replace them with new turf. Repeat every two months. Job done.

These work a treat - stop brown patches on the lawn from Urine, I’ve used them now for over 20 years! Easy to use just pop in the dog bowl. Change every 3 months - doesn’t affect water taste

Hi have bought dog rocks in previous years and this package came with three huge rocks in it stating put all three in the water bowl, if I had done this there would have been little room for water. I put one in and my dogs refuse to drink from the bowl as the rock takes a good portion of the bowl and I picked the smallest. I previously had small rocks I could place in their bowl that never bothered them so this was a waste of money as useless to me.

Always seems to do what it says on the tin, have two girl dogs and a beautiful lawn so this helps keep it that way
