Roger tells him "sit" and the dog just looks at him. Or occasionally collapses on the floor and goes to sleep.
Roger tells him "sit" and offers him a treat and the dog still just looks at him.
Our friend En came over and tells the dog "nang" and the dog sits.
Then just to make it better she says "kaah muuh" and the dog shakes hands.
No joke. Just turns out we have dog that doesn't speak English yet.
