I'm a little confused by this use of the word sentient. I understand it to mean "qualia-bearing", and I believe that chimps and other animals probably have qualia.

Not all creatures with Qualia are self-aware, and I suspect that that's the property he's trying to talk about.

Dogs feel loyalty, but they don't necessarily know that they do. That is to say, if you somehow got a dog to talk, it wouldn't necessarily start talking about it's feeling towards others, or its thought processes.
