Dogs and horticulture make uncomfortable bed fellows. You can count on the fingers of a mitten the number of dog owners who can boast grass which resembles the Centre Court at Wimbledon or the croquet lawn at The Hurlingham Club. Our own grass looks like Jackson Pollock in his thankfully little-known 'dog wee' period. So when the Dog Rocks UK team sent us a packet of their revolutionary solution to the problem of scorched grass, we were understandably keen to give it a go.

The Dog Rocks UK website www.dogrocks.co.uk explains all the science behind the product, but in essence all you need to do is take the rocks out of the packet and rinse them, place in your dog's water bowl and that's it! Change the water as you would normally and replace the Dog Rocks every 2-3 months. They are safe to use and work by changing the PH balance of your dog's urine to ensure that the resultant output(!) does not scorch your grass.

Dog Rocks take around 8-10 hours to work and despite having two enormous Great Danes, we have already seen an improvement in terms of the fact that what little remains of our lawn remains intact. Dog Rocks are great value at just £12.49 for a 2 month supply and are also available in the rest of the EU and in the USA where a 6 month supply costs only $39.99 with free shipping.

We were really impressed with the service too - the Dog Rocks arrived quickly and were securely packaged but most importantly, they worked exactly like the manufacturer's description.
