Second socialization state is from around two to seven months. It is very important to the life of our puppy, as at this stage the dog has to get used to the humans, other animals, noises etc. Like us when we are very young, at this age puppies do not have a feeling of danger and are curious about everything.
Keep in mind that at this time the dog, because of their curiosity, can destroy things at home. We must be vigilant and try to avoid these undesirable behaviors, as this may begin to undermine our friendship with our puppy.
