I think it's more conceivable to think that one dog actually pissing on another dog with varying levels of pressure is a more effective means of communication.... How could one dog ever possibly know how "hard" another dog pissed on the grass.... I mean, when I piss on the toilet seat, Mrs Cletus can't tell how hard I did it, even the dog can't tell how hard I did it, all Mrs Cletus knows us that I'm an !@#$ and I'm probably not getting any nookie....
Do you know where there is an all you can eat asparagus joint around OP?
