I went to a new clean worse than that! Telephoned customer evening before I was due, turned up to a big rotweiler and barely a patch of land that hadn't been dumped on by the dog, must have been a year maybe two years worth not touched, the smell was overpowering!
Didn't bother getting my hose out and left a note through her letterbox to say I changed my mind about cleaning her property forever as she couldn't even be bothered to clean up her dogs sh*t and my nose couldn't stomach the bad odour as it was excessive.
I felt sorry for the dog as it had barely a patch to lie down without being messed in it's own poop. Called the RSPCA as well so she would be checked out for possible neglect to her dog. I have a dog myself and I always clean up after her and spoil her rotten
