I have looked up "blue orbs" on the Internet (yes, of course, the apotheosis and repository of absolute Truth) and have discovered blue orbs to mean: " ... an indication of angels being around you, especially Archangel Michael as he resonates with the color blue." I also discovered different colors of blue mean different things: light blue means tranquility and pilot light blue means shielding. (Who in heck knows what 'pilot light blue' is. And who knows who decided what colors mean what?)
Of course, there is no science to this. But it's interesting.
In reading about the Archangel Michael, I discovered he's mentioned in Jewish, Christian, and Islamic texts. (Who knew?) And considered, among other things, to be the "field commander of the Army of God." (Thank you Wikipedia.) (OK, is it just me or does the idea of God having an Army sound just way too bizarre, nasty, and hateful? Must be the God of the Old Testament, that vengeful, spiteful, very human-like God, since we 'know' the God of the New Testament is a loving God. Not sure how Archangel Michael ranks in the Islamic text.)
Later (again in Wikipedia) I learn the name Mike (if he's visiting my dog, we're on a first name basis) "in Hebrew ... means 'who is like God' [by the way, that's a question, Christian friends, not a statement], which in Talmudic tradition is interpreted as a rhetorical question: "Who is like God?" (which expects an answer in the negative) to imply that no one is like God. In this way, Michael is seen as a symbol of humility before God." I like this explanation much better. My dogs would certainly be humble before God, if there is one. After all, dogs are named after God, only backwards.
I'm not sure how to interpret the presence of an orb that means both tranquility and shielding, but I like to think my dog will have both as he moves through his later years. Nor am I sure what the presence of these orbs means to my aging dog. Are they the spirit one of my other dogs? Tasha, perhaps, my beautiful German Shepherd who was Queen of the house, or maybe Linga, whom Boris loved without measure.
I just think it's interesting that my dog had blue orbs when no one else did. A

I wouldn't mind a blue orb myself, thank you.
