Small blinking and traveling lights

Small light in the sky, joined by 2 others of same size, color and round shape. Moving in quick unusual fast movements. Then disappeared and immediately reappear. Flashing on and off periodically. Guess is that we were fairly far away and they retreated toward the northeast away from us quickly. The trails were barely perceptible except for the full moon was in the sky to the right of the crafts thus the trail and the craft were illuminated much more so than on a moonless sky. This may be why we were able to see them so far away. Our dog continuously barked and went back and forth outside sensing something.
