The Protocol of P**

At the risk of delving into what might be considered vulgar territory, I need to ponder a bit about some of the less desirable attributes of dog ownership.  While walking Charlie late on a lovely Northern California evening, he stopped for a "constitutional" right on the sidewalk.  Of course I was prepared for this (I pride myself on being a very responsible dog owner.)  Certainly no one argues that in the event of a #2 stop it befalls on the owner to remove the offensive matter.  However after attending to Charlie's product that lovely night, I found myself wondering is there a protocol for pee?  

Although he's been with us less than a month, I have found myself in the vexing circumstance where my angelic dog suddenly squats on a neighbor's lawn.  I must shamefully admit that I typically mutter various encouragements to hurry along and then scurry out of the area as quickly as possible.  Is there a critical step here that I'm missing?  Am I obligated to carry some type of squirt bottle to alleviate the inevitable circle of burned out grass that follows a visit from a dog?  Please comment if you have advice on this.
