The Yellow Patches Won’t Stop on Their Own, Protect Your Lawn Before the Next One Appears.

Dog urine burn can ruin a lawn fast. One wee… one yellow patch… and suddenly your garden looks tired, damaged and embarrassing. GRASS GUARD+ is the simple, natural way to help stop those patches before they happen, giving your lawn a fighting chance to stay green, healthy and beautiful.

GRASS GUARD+ works by filtering your dog’s drinking water before they drink it, helping reduce nitrates, ammonia and trace impurities that scorch grass when concentrated in one spot. Lowering these compounds may help reduce the nitrogen load that causes those harsh yellow/brown patches. It’s the same trusted principle used by other natural “lawn‑safe” water treatments.

And we’ve made it safe and easy: GRASS GUARD+ comes in a secure gauze pouch, keeping the mineral nuggets contained so they never pose a choking hazard. Just drop the pouch into your dog’s water bowl no loose stones, no mess, no risk.

It’s 100% natural, non‑toxic, pH‑neutral, and won’t change the taste of your dog’s water. Safe for all breeds, all ages, and every home.

GRASS GUARD+ works best as a preventative, helping protect your lawn going forward. If you’re tired of watching new patches appear week after week, this is your moment to act.

Stop the damage. Protect your lawn. Keep your garden looking green, healthy and loved.

GRASS GUARD+ is the easy step that makes a big difference, and your lawn will thank you for it.

⭐ 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.
