Dog Fact #58

Looking to produce more male puppies in your litter? Science says to breed the parent dogs under a full moon! A team of Italian researchers at the Department of Veterinary Science at the University of Messina found that by studying 150 litters of Labrador Retrievers (over 900 puppies), found that more male puppies were conceived during the full moon! In fact, 62% of puppies were male when conceived during a full moon compared to only 41% in litters conceived during a new moon. Another study found a similar result with pregnant women who conceived during a full moon!
