There has been comment on the dog video, to the effect that it may have been burying not a friend, but rather a meal. This possibility cannot be dismissed.
All the same, I firmly believe that critters have souls. They won’t necessarily be like ours. Their minds aren’t like ours. But I am convinced they do have free will — again, probably not quite the same as ours.
Years ago, when I was living in Patterson Park, someone in the neighborhood owned this big, huge, very hairy, jet black dog whom they’d named “Bear.” I often saw the owner taking Bear for a walk in the park. From time to time I see auras, and I almost never failed to see, around this dog, a brilliant white aura extending three to six inches from its fur, in all directions. Whatever it may mean for a dog to be a saint, this was a saint among dogs.
