Three lights appeared, made very strange movements seemingly in a sequence before shooting off further than the eye can see

There were two lights in the sky as my family was leaving our birthday party for my mother in-law around 6 this afternoon and noticed they seemed to be incredibly low and didn’t make any noise that we could hear over the sounds of nature. Then out of no where another light appears above them and they all seem to slowly drift in opposite directions, then two of the lights shot away, almost replicating a shooting star, while the third light slowly continues to near us, we all just stared into the sky in awe, still processing what we all had saw then suddenly the light is right over top of us; then it disappears. Immediately after my 165 lbs Great Dane comes running to the house whining as if he had been attacked, doing everything in his power to get inside, once inside he wouldn’t stop trying to get under the bed in the spare bedroom, in the basement. From the time I first saw the lights to the point I let my dog inside over 2 hours had lapsed and none of u! s have any clue how.
