What to use to clean a yard

someone asking about what to clean a yard with, they have said it runs right into a storm drain. i studied pollution in uni so know what will happen if loads of chemicals go into the river everyday! so i want to suggest something that is going to get rid of the dog smells but be safe?

This stuff may be OK, it is pet friendly so must be kind on the environment too:

If I was to clean my yard I would use the wife to do it

Our lass would refuse but then there's always Jenny, as long as Inever let her out she will never realise that 50p is slave labour

Oh owww start running now boys

All I seem to be doing this week is running.......Laters!!!

why do we have to run , I can tease our lass once I am out of range of her chain , I had to keep it a 12 feet instead of 6 otherwise she wouldnt have been able to get to the kettle to make me a brew or put my tea on the table (its a big kitchen)

Make sure things like the kettle is nailed down otherwise that can reach out side the range.
