If I have a soul, then my dog has a soul too. My dog may pass away before me, but wherever he goes, I go too! Wherever I go, he will go. He is no different to any other (sentient) being on the planet. His only problem is, he is not as intellectually advanced, so he cannot deliberate such matters and be entertained by such matters.
Actually he is better off for it.

My dog has red blood, however, he is not the primary species on this planet, thus he is generally considered of a lesser importance in terms of a physical organism; most likely due to his much shorter life span and limited capacity for thinking. His thinking is his naturally developed intelligence based on his desire for survival and that, which makes him comfortable, in comparison solely to humans, I might add. If, like me, you trust your own instincts about the world, you might see that the history of mankind came out of the darkness of a lesser intelligence, that is, from a point when we too behaved more like the primate (animal). Since then we have constructed ideas like ‘soul’.

Now as then, we probably do have a soul, which means all animals have souls, which means my dog has a soul! And when he dies or when I die that which is carried out of life is the ethereal substance that I guess one can call, a ‘soul’. Of course, this does not make us equal with the animal, for we have naturally evolved beyond the animal to make a difference, however, we are made of the same stuff and the difference we make should recognize the elevated status of all animal life on Earth.
