I can only guess what it means, but I like to guess. And it is synchronistic because others have told me that they have seen a spirit dog/wolf at the same time as thinking of me. I am indeed connected to spirit wolves. I have seen them on many occasions. And I have experienced myself as a spirit wolf as well.

But I also think you saw this because you have been looking at my spirit photos and opening your mind to them. For some reason virtually all of the tree spirits I see appear as part animal, and quite frequently that animal is canine. They also sometimes look like serpents, or part canine part serpent.

So to me, that you saw the dog in the tree is just right!
