Having known Collies from my early years, I can confirm that they like their flock to behave in an orderly fashion. The only Collie that my Grandfather would allow into their home (Meg) was allowed to sleep by the range, but never permitted to lick bowls - tsk. Maybe Granny’s reason was to avoid competitive Dog-enticing, but I suspect she had other reasons. Can’t ask her, now.
Anyhoo, it’s time for bed. Good nights, Cellarites.
