This is 'CHASE'.
I commented to owner, after 9 days house/pet sitting for nearby relative:. "...that's the sweetest DOG I've ever known! A nice, and sincere compliment:
That black Poodle is instinctive 'medical companion', the kind they set up with diabetics, etc.
Followed me, into the BATHROOM, and plunked down, waiting, to go back to bedroom. He would even 'groan', as he realized, yet another (sleep interruption).
And another...and another.
Every 25 minutes...
