Give your dog two obedience sessions a day practicing whatever exercises the dog knows. These sessions should be 10-20 minutes long. Do not praise physically during this session. Use only verbal praise and keep the session moving. Have two formal eye contact sessions with your dogs each day.
Problem dogs look at their owners only when they feel like it.
Up the eye contact. Put a leash on. Sit the dog. Do not yell. Once you get this moment, end with light verbal praise.
