LAVA-LITE GRASS GUARD+ is a natural volcanic mineral blend designed to help prevent dog urine lawn burn — the yellow/brown patches that appear on grass where dogs urinate. This is a lawn care product for pet owners, not a food or supplement for your dog.
It works by filtering your dog's drinking water before they drink it, reducing nitrates, ammonia and other trace impurities. Since these compounds are excreted in urine and concentrate in one spot, lowering them in your dog's water may help reduce the nitrogen load that scorches grass. This is the same principle used by other natural "lawn-safe" water treatments on the market.
100% natural, non-toxic and pH-neutral — Grass Guard+ doesn't change the taste of your dog's water and is safe for all dog breeds. As with similar products, results can vary between dogs and lawns, and it works best as a preventative measure going forward rather than a fix for existing dead patches.

⭐ How To Use
Fill the supplied gauze bag with half the pouch contents and rinse. Place into a 2-litre water jug, fill with fresh water, and leave to stand for 12 hours. Use the infused water to refill your dog's water bowl going forward. Replace the contents after around 2 months. Always ensure your dog has access to fresh drinking water at all times.
⭐ FAQs
What is LAVA-LITE GRASS GUARD+? A natural volcanic mineral product that filters your dog's drinking water, aiming to reduce the nitrogen concentration in their urine that causes lawn burn. It is a lawn care product, not a dog food or treat.
Is it safe for dogs? Yes — 100% natural, non-toxic and pH-neutral. It doesn't alter water taste and is safe for all breeds.
How long until I see results? If it works for your dog and lawn, most people report noticing a difference within 1-2 weeks, with fuller results after around 4-5 weeks of consistent use. Results vary between dogs, diets and grass types.
Will it fix patches that are already brown? No — it's a preventative product aimed at stopping new patches forming going forward. Existing dead grass will need reseeding or normal lawn repair.
How does it actually work? It filters nitrates, ammonia and other impurities out of your dog's drinking water before they drink it — the same principle used by other natural "lawn-safe" water treatments.
How often do I need to replace the contents? Replace the gauze bag contents roughly every 2 months for continued effectiveness.
Can I use it with multiple dogs? Yes — with multiple dogs you may want to prepare infused water more frequently given higher water consumption.

My lawn hasn’t looked this proud since before we got the dog. (Sorry, Buster.)Bonus?It’s 100% natural, so no need to worry about mystery chemicals turning my pets into glowing mutants. And the cats?

Just healthy grass and happy paws.
Brilliant product. i will be buying more thanks
this works & guidance on how much to use for multiple dogs getting through more than 2 litres a day or for how long to leave in water after initial activation. Great stuff
We have 2 x Pekingese dogs and they have been known to burn the lawn with their urine at certain times. This stones are a good product for helping to reduce the effect that dog urine can have. We have used larger version in the past but these smaller pieces are very easy to use and store. They are not too small for our dogs but may be an issue if you have a larger breed. Good value for money solution compared to costly lawn repair work
Rather diificult to judge the effectiveness of this product, have been using it for the last two weeks, the listing states you should see results in four to five weeks and couple this with the recent dry and now very hot weather our lawn is going brown in places the dogs never go. My daughter has been using lava rocks in her dogs water for the last couple of years and swears by them, I also stay in a holiday cottage where they have these and given the number of dogs who stay there the lawns are perfect with no evidence of urine burn.
