I read your past thread where your vet tells you Our vet said that under socialized is a understatement. He was either abused or totally ignored at the critical time he was with the breeder.
Googledog behaviorist and type in your zip code, you should be able to find one near you, you can also call your vet and ask them if they can recommend one. Now you do not want obedience training you want a dog behaviorist there is a big difference between the two. At a year old there is still a chance of turning this dog around with proper and diligent training.
