Fireball with a 3’ blazing tail

I was on the front porch (porch light on and light near walkway) the background was dark - took our dog out for the last time before bed. I stood on porch and the fireball with a blazing tail was 30’ in the yard in front of me. It lasted a brief moment, then another exact thing came behind it. They were going in the direction of my dog. The fireballs with a blazing tail were approx 30” off the ground. I called my dog to go inside for the night as I wasn’t about to go in the yard to examine what I just saw. My dog was skittish many days after this event. So weird! I know what I saw and it was real!
