So sorry to hear about Buddy. I would definitely put up flyers. Call all the animal shelters, the police department, and notify any and all neighbors. I am sure Buddy was just scared and ran. Check the lost and found on petfinder for your area, and be sure to get this info out to as many doodle boards as possible. I was just looking at an Arkansas shelter, and saw a terrier mix in there that I am sure is a labradoodle, but a female.
