I have a question for you breeders or others that have had a lot of dogs. I keep puppy growth charts on all the pups I raise and keep, but don't have enough to make an educated guess! Is there data proving that the male puppies grow longer than females? I have the impression from what I've seen that they do, but looking for more proof! I had my pups sister here the other day and while my male pups lower canine teeth had recently just come out (leaving blood on the other playmates), I looked at his sisters teeth and her same adult teeth were already about a third the way in! So, I'm guessing he was a week or two behind her! They were 19 weeks old at the time of inspection!
Thanks, Steve
