When to start education?

Puppy education starts at his birth.
Good behaviour is acomplished by dog socialising, introducing the environvent to your dog and spending as much time as possible with it in as many various situations caracteristic for an urban environment.
Larger dogs are advised (in an earlier age) to take the basic programmes of socialisation with an expertised course leader, working alongside with other dogs.
The owner has to work with his dog with help from an expertised person. BASIC DOG TRAINING WITHOUT THE OWNER IS NOT EFFICIENT. The owner working with an experienced person allows the dog to learn obedience with the owner's orders not considering all the circumstances (dogs, cars, people, cats...), the owner at the same time gets knowledge about treating dogs and working with them. If the dog was sent to training without the presence of it's owner, it is going to behave as usual when back home, trying to be superior to it's owner, while he still has no authority and knowledge how to treat the dog properly.

Basic training classes

Professional "dog trainers" train the dog's guardian on how to train his dog. Although it is also possible to send a dog to a training school, the owner must learn what the dog has learned and how to use and reinforce the techniques. Owners and dogs who attend class together have an opportunity to learn more about each other and how to work together under a trainer's guidance. Training is most effective if everyone who handles the dog takes part in the training to ensure consistent commands, methods, and enforcement. Classes also help socialize a dog to other people and dogs. Training classes are offered by many kennels, pet stores, and independent trainers.
Formal training in classes is not always available until the puppy has completed all its vaccinations around 4 months of age; however, some trainers offer puppy socialization classes in which puppies can enroll immediately after being placed in their permanent homes as long as disease risk is minimal and puppies have received initial vaccinations. In most cases, basic training classes accept only puppies who are at least 3 to 6 months old. It is however recommended to start training as soon as the puppy comes into your home. A better way than groupclasses is "In Home Dog Training", with companies who will have trainers coming to your home, you can start training as early as 8 weeks and set a great start to proper housebreaking procedures and building a good consistent start.
A puppy requires discipline, consistency, and the patience of its owner. Owners should take time to train their puppies and take steps to make their home safe. The puppy training phase is integral in raising a healthy and happy dog and keeping a safe and fun home environment.
Puppies need consistency more than anything else. A stable diet and clear expectations will help the puppy learn what it is expected. Dogs are expressive and may communicate needs by biting, whining, and getting fidgety. The owner's response may contribute to a healthy, obedient puppy. An important principle is that the best way to change a puppy's behavior is to modify one's own conduct. Giving a puppy toys that are similar to household items he likes to chew may facilitate easier puppy training.
An integral puppy training issue is house training. Various methods of housetraining will work although the key is to be consistent. With regularly enforced rules, litter box, crate, or paper training can be successful.
