My cocker puppy flies home next week. He's out of an unusually large litter of 9. She was huge and whelped 6 days early.. One was stillborn, 5 were normal, 3 were really really tiny. All the tiny ones died within 24 hours even being fed by the breeder, extra diligence on keeping them warm. She tried, they just weren't developed enough.
Good luck with yours.
