Dog RocksUrine Patch Preventer (200g) / Natural Dog Urine Neutraliser for Water Bowls, Grass Repair, Urine Burn Patch Repair

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!!!

Nice item easy to use accurate description

I've purchased these before and have been more than pleased with them.. However, this time the rocks are too big. Normally I put them in my dogs water dispenser but as you can see from the photos this is not possible.As they are so big the water doesn't cover them... I've tried a couple of bowls.The mess my dog makes licking around the rocks is not good.Bring back small rocks as they defiantly do work.

Hopefully will work dog peeing on new lawn so hopefully will sort this out

And if you stop and think - why would they? It's not a filter like a mountain spring filtered over thousands of years; it's not a chemical reaction that's going to work as quickly as you fill the bowl each 12 hours....so I bought a filter jug, at half the price, and now have filtered water for my dog, as well as the kettle and the coffee machine. AND it has helped the urine burns. Brill.

Don't know why the review page would only take 4* because it's a 5* product?Been using it a month now and we're totally amazed at the difference in our lawn, no more new yellow burnt patches and the old ones are almost gone. I bought a jug thingy from The Range for less than a fiver and it works a treat, got to say you have to be consistent with only letting your dog drink your water but it no great hassle once you get in the habit of taking their water with you outside of your home. Highly recommended.

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.

Bought these under duress, my wife wanted them. I argued with my wife (I really should just accept that I am wrong) as I could see reason why putting stone in the water bowl would stop the dogs killing the grass. But for the time we were using these there was a noticeable difference in the garden. I don't know how these work but they do.Stopped using as, at the end of the day, it works out excessively expensive just for a bit of lawn.
