Puppy training is a huge subject and we will deal here with some critical points.
From the moment a puppy is born it is learning from its parents, litter, environment, breeder and associations. The quality of the breeder is critical in this regard as they should have the experience and application necessary to give your puppy the best start in life.
By the time your puppy leaves the comfort of its breeder, it should have had all the necessary health care, handling, cleaning, social interaction with people and other animals possible (within health constraints) during its first 8 to 13 weeks.
When the puppy arrives in its new home, understand that the stress is extreme, and its environment must be as warm, comforting and understanding as possible.
Puppy training in the home is its primary source of training, so the more time you have allowed for being at home the better. You will need to decide on some household rules, make them clear and uphold them strictly. Be aware that your puppy has poor control of its bodily functions until around 6 months or more, and there is a vast amount of good information available through myself or others to help overcome bad habits forming.
Your hands should be the most important contact and communication you have with your dog, as it is this physical connection that will give you the best mental and spiritual connection. Then comes the way you use your voice, and the timing you use to negate confusion for the puppy. Puppy training requires more patience and understanding, realizing that the puppy has a short attention span. Eg. I like to train puppies for 30 seconds at a time, with 3 minutes of relaxation and recovery time down with the pup, followed by another 30 seconds and 3 minutes relaxation and so on.
Start getting the puppy used to having a collar on and using a lead around the house, especially the front yard if possible. As soon as you are able to take the puppy out into the community, do so, exposing it to every experience you can think of. However, have the puppy walking as much as possible and refrain from protecting it, and encourage it to meet and investigate.
Teaching the puppy to do things with treats is easy, and can be very successful if carried out properly, but it will be your hands, voice, timing, competence and confidence that will truly connect the puppy to yourself.
You need to ask yourself, do you want to teach your dog tricks, or is it a very strong relationship you are after. That will determine how you go about training.
