Interesting. I have seen dogs suck to a retired station enroute to a flyer. In some cases, there was noise or movement from that station that I am pretty sure was a contributing factor. I don't recall it ever happening to me, but to other dogs, yes.
I have also seen cases where a loud noise behind the line has caused a dog to turn its head at an inopportune moment, and the dog did not see the full flight of a mark.
That being said, as a competitor, you take what you get and do the best you can with it.
As a common courtesy, others should do their best not to be the cause of excess distraction when others are running.
