I’m certain that’s for time constraints on TV. Have you ever been to a live dog show? It’s like running an 8-hour marathon, or a day spent judging animals at the County Fair.
I like this one because of John O’Herley as one of the Hosts. :)
I’ve been watching Westminster, which is 2 nights for best of breeds, for decades.
If the show isn’t going to air all the breed winners, it’s a waste of time.
