This was an announcement today at the dog show.
The announcer went on to mention that there were no parents nearby, but they needed to tend to their crying baby.
The walkway mentioned was a street in the show grounds that was lined on both sides with vendor booths, and set ups, and on the one side the show rings were behind the set ups. The baby was on the other side.
I have known people whose kids crawled into the crates or expens and took naps while they were in the ring, but their children were ringside, not far away.
