Product description

Dog Rocks filter out impurities from water such as Tin, ammonia and nitrates. These impurities are usually passed out through urine, and when grass comes in contact with these elements it results in urine burn on grass, resulting in a dead, yellow patch on your lawn. Dog Rocks give your four legged friend a cleaner source of water, while eliminating urine burn on grass this will result in the stop of those nasty burnt yellow patches on your lawn. Without the impurities in the water, Dog Rocks actually help your dog fertilize your lawn! This is great for you, your dog & your lawn!

    I’ve used these for the past 2 years for my backyard and when I run out my grass goes brown within a couple of weeks. Terrific product that works and my dog loves drinking from her bowls with them in it. Looking forward to getting my delivery to save my lawn so it can look as lovely as before. Never running out of these again. Keep up this great product. I love a nice green lawn!

    we have a retired racing greyhound..the worst dog for urine burns ...trying this has worked to an extent ..the burn marks are still there but not as harsh ...maybe i should use double the rocks
  • SueC says...
    We have been using this product now for about 2 years with our old female Jack Russell. Her urine was burning the lawn everywhere she went and we were so skeptical initially that anything would help but must say these rocks have helped greatly. We now have lawn growing where none would grow for many years and we can tell when we need to replace the rocks as a burn mark appears "suddenly" if we have left the rock in the water feeder for more than two months. As we put our rocks inside her tall water feeder they do not bother her at all- she probably doesn't even know they are there. They are like "magic rocks" as far as we are concerned. Happy to recommend them.

    Was a bit skeptical at first but thought it was worth a try. We have 2 dogs, one male and female so often a double whammy in the same spot. After reading reviews I thought I would try a recommended method, I got a new bucket with lid, filled as per ratio and instructions however I let this stand overnight before using it. I like to change our dogs water everyday, so I don't top up as per the instructions, I just do this process everyday. I don't put the rocks in the dogs bowls I just keep them in the water bucket and change it everyday. They do last the 2 months as per instructions, I tried to stretch it out a bit more but we started to see the urine burn marks again. Really does work and my husband is glad his lawn is looking green!

    This worked well for my old dogs. The cloths line actually started to grow grass under it again. You do have to add them to all of their wter bowls though, for it to be effective.
