I bought these as my grass was a mess with my Bob the Dog peeing on it and leaving patches. I was a bit sceptical about the dog rocks but oh my goodness, thy work a treat. I no longer get patches. Bob wasn't put off his water with them in it either. I would highly recommend them.
I am very I.prrssed with the results and would like to repeat the order
Exemplary product excellent results
Continued improvement in lawn
Used this over a month. Dogs drinking no problem. Grass is moving from yellow to green. Does what it says it does!
