There were 3 dogs. 4 if we count Carbuncle.
Lunafreya had 2 dogs. Pryna and Umbra. They're not really dogs. They're "messengers" of the gods.
Pryna (white) gets the most screen time, as she ties in with Prompto's backstory.
Umbra served as a kind of Junction Machine Ellone, to revisit areas from the earlier chapter if only "in memory".
Carbuncle was only featured in the Demo, in Noctis' dream.
And finally, there was a demon dog seen in the "Omen" trailer, which was all the King's Dream.
