Just looked at the program. This will be the first time in years that I will be showing two.
Looking at the program, it's going to be close with their classes. I rather show my own dogs, but other than have a friend show one if their ring times end up overlapping, is there anythiing else I can do? Do you tell the both stewards you might be late as their looks like there might be a ring conflict? At what point aren't you allowed in the ring late? For example, you miss the first "take them around together" or can you enter the ring up until the time the judge has finished all the individual exams? It's very special to me to show both myself for really sentimental reasons.
Assuming you are in another ring & the second dog's class is starting..... Have the person who is taking the dog in for you tell the steward that you will take over as soon as possible & ask that he/she be allowed to go to the end of the line.
