Dunwoody Police posted pictures of the wreck to Facebook.

"The interstate is back open. Quick shout out to the officers of C Team making sure that all injured parties, including man's best friend, got to appropriate hospitals. There were 4 totaled vehicles, 3 injured humans, 1 injured K9, and plenty of debris to sweep up," the department wrote. "But again, all is clear. Hopefully the rest of the morning commute is better."
