Cats can - so why not dogs ?
Whats the time, Mr Wolf!
Highly likely! Trained dogs for the infirm can perform all sorts of tasks, so, why not?
Our dog used to sit on a park bench by our gate waiting for me to come home.
My dog roamed free on the farm but was always back home waiting for me near his kennel when I walked up the road after work.
I knew someone who had a watch dog.
