While obedience training can be accomplished at any time during a dog's life, it is easier, faster, and more fun to train a puppy. At 7 weeks, a puppy's brain waves are the same as an adult dog's. His/her capacity for learning will never be greater. Puppies can join the class as early as 10 weeks old, providing their vaccinations are current.
scientific studies state that in order for puppies to develop into calm,
confident, well-rounded adult dogs, it is essential for them to receive
proper socialization and obedience training between the second and fourth
month of development. By implementing early training, potential behavioral
problems may be prevented before they become ingrained behavior patterns;
using prevention rather than correction.
