Dog Rocks – naturally brilliant I hope
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!

Great but replace rocks every 2 months
These work for a Jack Russell size dog but I put them in a jug of filtered water in the fridge and top up the water bowl using the jug, I use both rocks in the jug and replace every 2 months, one month I forgot and went over by 2 weeks and my lawn started getting burnt again so you need to replace the rocks every 2 months without fail. They are great if you keep on top of the routine and the lawn looks great!👍

So far for us, they’ve not worked particularly well
The brown patches have reduced slightly, but this could be because it’s done nothing but pour down for weeks here diluting his urine as he’s doing it. He’s also out and about a lot more, so not always peeing on the lawn. Hence a 3 star review because I can’t be sure. Otherwise, I’d advise buying with the approach that it won’t harm but it may not be a miracle fix, especially if you have a large male dog. I do know people with smaller, female dogs who swear by them. ** We have them in all his drinking water bowls and have given them a fair shot time wise.

Don't Waste Your Money
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.

600g pack rocks are too big.
We normally purchase the 200g pack which has 2 or 3 rocks. This time we purchased the 600g "better value" pack It arrived with just 3 rocks in the bag. Each weighing about 200g. The instructions clearly state 100g per litre of water. We tried breaking one of the 200g rocks with a mallet but we only managed to break off very small slither. Not good. Back to 200g packs next time.

Simple, Effective Solution – Really Works!
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!

Tout à fait efficace
Nous voulions tester le principe avant de mettre une nouvelle pelouse et nous sommes tout à fait convaincues. Aucun auréole brune dans la pelouse. À recommander.

Works better than the treats
I think these are working properly, compared to the treats you give to the dogs. They're very easy to use, and our dogs don't notice the taste difference anymore. At first they thought the rocks were play toys so they took them out of the water and brought them outside. There is no added smell. They don't take up much space at all in our water container. We've noticed less brass burns since we've been using these rocks.

No yellow spots in my yard.
This works great!!! I have two dogs, a black lab and a border colley.collection. My yard is Kentucky Blue Grass. Once I started using the dog rocks I no longer have any yellow spots on my yard. The border colley is female which I'm told is worse for the yellow spots. You wouldn't know it from my yard.
