I've heard that newborn weights don't always predict as well as later weights. So many breeders have told me the runt of the litter turned out to be the biggest. Birth weights depend so much on the position and nourishment in the womb. I think triple the 8 week weight and or double the 12 week weight and give or take a pound, might give a better indicator. You don't say how big the damn and sire are, but that again is only one indication. They pass on their parents genes as well, and if a 5 pound dog was the smallest of a line, he could throw bigger dogs. |
