Apes and homo sapiens have a common ancestor that is almost certainly extinct. Where do you get this "blood related" nonsense?
Of course, theists believe that humans have souls and animals do not. Well, perhaps except the folks that insist that All dogs go to Heaven.
There is no way to prove that any organism has a soul. Souls are rather like time travel: they are ever so useful as narrative devices.
I find it amusing that although the Biblical character known as "God" has been constantly disappointed in human behavior, humans have been quite successful in making dogs through breeding into whatever they wish them to be: guardians, companions, shepherds, defenders of food, and both hideously ugly and extremely ornamental. Have humans taken free will away from canines? I see no evidence of it. There is no doubt that a dog can be far more loyal to his owner than humans can be to "God".
