Lost Black Lab in Presidio, Boerne - Help Needed!

FOUND DOG!! Found this guy wondering the neighborhood, large black lab with white spots on neck. He has a shock collar on and no tags. Is a sweet boy but definitely missing home. *IN THE PRESIDIO NEIGHBORHOOD AREA IN BOERNE I can’t hold him for long, I already have 4 dogs and a cat, if someone could hold him until we find his owners that would help out so much!! I already have an active intake form for him at the Animal Defense League
