Whistle

Some whistles are happy-oriented, like when someone wants to offer over-the-top praise for a hero at a public event by placing fingers in mouth like the Texas hook-em-horns symbol and belt out a sound higher pitched than a finishing note from Celine Dion.  Dogs don't whistle and that might not be a bad thing.  A loud bark is the near-equal anyway.  Whistling is mainly negative, think referees, and dogs just stay positive mostly.

Memory loss

Dogs, to the best of our knowledge, don't remember that they bought lottery tickets, get distracted while walking to get the lottery tickets, not recall any remote thought of ,lottery tickets, think about what they couldn't remember and 45 seconds later re-trace steps to realize, oh the lottery tickets are on the counter.

Keefer or Tom

Dogs can't have a head-debate over who runs toward fear better:  Cruise in any action flick ever, or Keefer in "24" except the held-captive seasons.

Tired act

Dogs don't reuse tired comedy routines, like popuar Monday night shows, where hilarity is anticipated when someone has a heart attack.

NBA

Due to the opposable thumb issue, the dog's are not so concerned with the NBA playoffs.

Invoices

Dogs are better off than people as they never have to deal with the term invoice.  A dog never gets and invoice.  No dog has ever denied payment on a legitimate invoice.  There are no invoices in their heads, ever.

Just saying....

Never saw a male dog walking around who wished he was a female dog.
