Puppy Kindergarten is for socialization, dog-on-dog learning and to lay a foundation in a positive manner during the most impressionable time in a dogs' life.
Very few dogs NEED private obedience classes. Extreme dog aggression, extremely shy and/or fearful dogs, dogs whos handler cannot safely handle the dog in a class......these are examples of dogs who would benefit from a few private lessons...but IMHO; a dog, who can execute their commands in a class situation will be more apt to do the same in ANY situation.

Modern day Koehler IMHO.
