According to fossedata and the National website:

There is an error on the National Dog Show's information leaflet
which has been sent out to all exhibitors. This states start times
of 9.00 a.m. for Days 3 & 4 of the show. The Society would like
to confirm that judging on all four days will commence at 10.00
a.m. for all breeds which are first in the ring, unless a 9 a.m.
start for the individual breed is specified on the information
leaflet. If there is any confusion please email the Secretary at
thenational@btinternet.com or ring on 01206 391984.
