Trooper is a smart cookie, even for a service dog. He has figured out how to snooker me into feeding him prematurely.
He normally gets his dinner at about 4:30 p.m. But he starts to get hungry about 3 p.m.
After that hour the last few days, he has been throwing himself up on me, then at my "What? What?" leading me not to the source of a sound (such as the phone, the door, or the call of my name) but to the kitchen and cocking his head at the food bowl.
I'm dealing with that by following him to the food bowl, then saying nothing but ignoring him pointedly and walking back to my office. Sooner or later he'll get the idea that I'm on to him.
