This has happened in my breed. But we have been told that we can ask for a refund of entries, not that we will, but was interested to hear this and does it only apply to Crufts.?. I have not heard of this before.
Remember being at Crufts and waiting for the first class when we were told that our judge had fallen as she left the judges reception and they asked one of the exhibitors to take over - she did but said after that it was a shame as she had been looking forward to going shopping and having her hair done when it became her turn to be invited to judge at Crufts. Shame really she had to judge in her showing pants and jacket but she looked fine as always.
