Growing up my dad would regularly commute out of town for a week, always leaving Monday morning and returning Friday night. My dog would be waiting by the garage door on those Fridays, but only on Fridays, she never waited any other day of the week.

So some dogs are definitely accurate sources of information regarding weekdays.

Idk man, dogs are actually very good clocks. Not this one, but most of them.

This dog is a Professor of Time, you really gonna tell me he’s wrong?
