Missing dog spotted in Uptown

About 15 minutes ago spotted a dog with leash and harness running without its owner on the street in Uptown. Looks like a white colored pit mix, maybe 40-50 lbs. Tried to trail it but lost it after about little while, last seen running north at Leland and Clarendon. Please spread the word if you know this dog or know someone who is looking for them. Keep your eyes peeled if you’re in the area!
