So, to re-cap, our Kerry is respnsible for the following:
She appears to own a lab/collie x who just happened to mate by accident in the park with a full breed collie, and she is selling the litter.
She appears to have owned another bitch, Maisie, a lab/spaniel x, who had a litter, resulting in the staff x puppy Yogi.
She has 'lost' Maisie and Yogi in the same unexplained incident.
She (or someone close to her) is selling a 6 month old Ridgeback (though I can't actaully see a ridge, and he/she is liver nosed like a vizsla) and they seem a bit unclear as to the sex.
And now she is trying to re-home a 2 year old mastiff. It doesn't appear to be hers, but she is very cagey about who it belongs to.
