飼い主が自宅に居ない間に、大変な事をしてしまった犬の様子です。
飼い主が、犬の方に視線を向けると、後ろめたい態度を見せます。一応、犬でも反省しているのかもしれません。普段の飼い主と犬の信頼関係がしっかりと伝わってきます。

It looks like a dog that has done a lot of work while the owner is not at home.
When the owner turned his gaze toward the dog, he showed a guilty attitude. For the time being, even dogs may be remorseful. The relationship of trust between the owner and the dog is clearly communicated.
We will never know who did it
