Probably true, but the point was that the daughter was capable of quick multiplication, the age of the dog was..decidedly a minor detail.

Classic HN

Parent comment belongs in the hall of fame right next to the classic "Dropbox is trivial—it’s just an FTP server under version control":

I see your "classic HN" and counter with a "I'm one of today's lucky 10000!".

I was taught the 7 years rule as a kid and only learned as an adult that it's an average, not true for all dog breeds.

It's also not really true for young dogs. A 1-year-old dog of most breeds is reproductively mature, whereas a 7-year-old human is not.
