If your dog won't eat his dinner, lean over it and make chewing noises. You don't actually have to eat the food, but I suspect this might be a more effective tactic. I don't think this works on children, though, so it's hard to say. I don't think the "Here comes the airplane" technique works on kids either. But it might work on dogs. I'll let you know. When my dog Pounce was a puppy, he wouldn't eat his kibble until I took it from his bowl and put it on the floor. I'd try that again now, but it would be too messy as we give him tripe now with his kibble. He won't eat the kibble without the tripe. You might say he has me whipped.
He is almost finished his dinner. I don't have a camera to take pictures to prove this to you, but even if I did provide pictures, you could say that I ate the food myself. Or threw it out.
