If your breed is anything like mine, double coated then they wil look their worst coat wise when pups are about 12 weeks old. My bitch had her pups 12 weeks ago, and is threadbare coat wise, but almost fully fit body wise. I am hoping she just muight be showable for Midalnd counties in 3 weeks, but it is doubtful wh will grow enoguh coat in 3 weeks.
So my answer would ahve to be at least 4 months from birth of pups, but probably up to 6 months from the birth fror them to look really good if they are a coated breed, which is probably just around when they have their next season.
