Snap, bulbaholic, I was about to say do you have a dog, particularly a bitch. If you don't, did you walk on the lawn during winter when it was covered in snow? When did the brown patches first start appearing? And a photograph would be very helpful.

Or, like us, does your neighbour's bitch pee on your lawn?
