Well, there is an older mammalian brain and a newer mammalian brain (not to bore anyone to death with an anatomy lesson). The older part of the brain is devoted to things like eating, sleeping, AND emotional responses and all mammals share that. The newer part of the brain, which humans have a lot of, is devoted to thinking. So, I think doggies are mostly emotion!
But here's a fearless disclosure.... My springer spaniels are half sisters and when both of them were puppies, I swear I could clairaudiantly hear them say things like, "Mommy is good." Now I know that sounds nuts and I am a very logical person. So, what I'm implying is that doggies are mostly emotional with a little bit of thought! That's it, that's all I ever recall psychicly hearing, but I heard it quite a bit!

P.S. This is also what Spirit thinks of Averi...."Mommy is good!"
