There is no evidence that dogs have the kind of complex emotional lives and value systems that we do. It's one reason why we love them so much, in fact. They are neither "good" nor "bad." They don't hold grudges, act in petty ways, or seek revenge. They read our moods, but not our minds.
Sentiment: POSITIVE
It's important to remember that the animals are not grieving with us. They're very accepting. They're not lying there thinking 'How could you do this to me? Why aren't you keeping me going?' Pets don't do the human things of guilt and anger and recrimination that we do. They come and go with great acceptance.
