What Are the Main Factors Affecting a Dog's Personality

Poodle (Detailed Introduction)
Raising dogs is actually the same principle as educating children. Habits and personality are cultivated from a young age. Even dogs of the same breed or litter can have different temperaments and personalities. So why is that?
The main factors affecting a dog's personality are as follows:
1. Innate personality (individual character)
2. Family environment (whether many people interact with the dog, whether other animals are often seen nearby)
3. Family members (whether it is a lively big family or a single person)
4. Methods of training the dog
5. External environment (whether an apartment or a detached house; a quiet environment or a bustling place)
6. Other reasons (whether other animals are also kept). As the puppy gradually grows up, the influence of these factors forms its own personality.
Further investigation shows that only the first cause comes from the dog itself; the other five are related to the owner.
This shows that a dog's personality largely depends on the owner's method of education.
