I was sceptical when I first tried these but it certainly works and is much easier than trying to get the dogs to wee in a particular place.
Sceptically I bought a pack. Now on second pack. Still have spots but soooo much better!
It's still early days but this product looks to be working! Our rock came as one large one so haven't had to worry too much about our puppy taking it out of the water and swallowing it but I like the idea of keeping it in a separate container and pouring off the 'treated' water daily. It's all natural - which you gotta love!
Magic. Had low expectaions but no more yellow patches on the lawn!! Wouldn't be without them.
Great product have been using the rocks for awhile no brown spots on lawns would recomend to all dog owners. everyone happy
