Puppies are always Learning
The most learning is between 4 to 16 weeks old.
Normally at 8 weeks old they come in to your family.
Firstly introduce them to all kinds of sounds and places, especially travelling in cars, and walking on a lead in the house and garden, It is important as they will learn the lead is a positive item, by using rewards.
Take your puppy out to meet people and situations.
Also they will be looking at you as there pack leader / mother / father.
Puppies also need boundaries so this is the time to teach them things like going in to a dog crate at home , going to the vets and getting weighed and seeing the vet.
Some Vets have puppy clubs that you can join. So grab the chances as this is the most important part of training .
