My old and long departed Blue Heeler, Charlie, and I always had either a cup of coffee or glass of Iced Coffee Milk, well he had his in a bowl, for smokoh ( morning tea) or when we got home after a walk.
He'd be right by my side when I was working outside gardening, etc, and about 1 hour to 1 and hours into the job I'd get a nudge from him suggesting, in my opinion, that he expected smokoh to be served up soon.
