no a few days earlier or a few days later it perfectly fine. Some say the average is between 10-17, but from my experience it was on a average of 14 days. Good luck with your puppies and have fun. When my mom bred a litter she had puppies that didn't open there eyes until they were a month, now that's unusual.
