Just shaking my head:
I just checked Craigslist for border collies (I do this every few months, just because), and saw a listing for rehoming of an middle-aged border collie. The woman found him as a stray about a year ago and admits that he is NOT up-to-date on vaccinations and is not microchipped.
But here is the kicker: She doesn't know if he is neutered. Say what???
