Who will take the lead

I thought it would nice for you to see the rest of my dogs all together.
Ko Ko is the oldest at 12, unfortunately she has degeneration of the spine, which makes her very wobbly on her back legs, she is part blind and was given up at the age of 6 due to breaking her leg and not being suitable for showing any more. She is the happiest dog you could meet even with all her problems.
Mimi is top right at 11 and is just a total show off and a diva.
New addition Mollie is bottom left at the age of 4 , she is just so cuddly and dare I say it very favoured by me.
Even newer addition Harry bottom right at the age of 2, is still finding his feet, but is a very friendly lovable boy.
The pack are a little lost at the moment as there is no pack leader after recent events
