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 BenefitsNatural filtration – removes compounds that cause urine burnSafe for dogs – no additives, chemicals, or side effectsEasy to use – rinse and drop into your dog’s water bowlLasts ~2 months – one pack treats up to 2 litres of waterWorks with most diets – especially effective with kibble-fed dogs⚠️ Watch OutsNot a miracle fix – results vary depending on water hardness and dog sizeRequires consistent use – top up water daily, replace rocks every 2 monthsNo 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!

These might only work if you can control where you dog drinks from 100% of the time. Mine drink from various places meaning my lawn still has brown circles on all over. So too expensive for reducing the odd circle

With a Great Dane and, until we had to say goodbye to him at Christmas, a cocker spaniel, our garden sees - shall we say - a LOT of err “attention”!!All I can say is that I have no idea how but these work!!!Brown stains on the lawn disappeared entirely within just a few days; we’ve been using them for about five years now and the difference they make is insane - and weirdly, we know when we need to replace them as after maybe 12 months or so, we start seeing brown stains again. Change the rocks and the stains disappear in days!Note that we inadvertently purchased a different brand recently and realised immediately our mistake as that was more like gravel. These are much larger rocks and don’t fall apart.Don’t be disappointed at paying for what appear to be three or four large pjeces of gravel - these genuinely absolutely work!Pic of the dog … if they can handle him, they can handle anything!!!

I imagine the meeting between the marketing team went abit like this:“People who hate having dog urine burn on their lawns need a solution right?!…..So how about we just tell them to buy some rocks off us and put them in their dog water?”“Does it work?!”“No, but they’ll be desperate at this point so they’ll try anything!”I’ve bought many useless things in my life and this is up there with the best of them!

These work! I have a Cavachon and she pees on the lawn all over.I put these rocks in a 2-litre jug, regularly topping up, and fill her drinking bowl from that, after whatever the magic is in the rocks has been absorbed. She doesn't drink from anywhere else.I can tell when the rocks have stopped working because the brown patches come back with a vengeance. Within a few days of replacing them the lawn is perfect again.I can't understand why people would just put them in the dog's drinking bowl? Won't work!

I've used these before and had good results, but as noted by other reviewers, there's no guarantee. This latest pack aren't helping. I've delayed leaving my review to see if spaying makes a difference, but it doesn't. Still getting patches of dead grass on the lawn. As I know they can work, will try again with a new pack.

Good product seems to working , no more burnt patches on my lawn . I had to fix the existing burnt patches from my female dog , definitely no new ones after 5 weeks of using
