Dogs are aggressive, non-aggressive dogs are just relative

 All dogs are aggressive, but different breeds of dogs have different aggressiveness and different probability of attack. 

Aggressive behaviors of dogs can be roughly divided into the following categories:

1. Dominant attack

Dominant aggression is the most common aggressive behavior in dogs. Some dogs with strong autonomy and dominance will challenge the authority of their owners and want to become leaders. Some dogs may have realized that they are being controlled and want to understand their status in the family through this behavior. 

2. Fear attack

Dogs that have been abused, scared, and left a psychological shadow, or partially adopted dogs will show this kind of aggressive behavior. Because they have not recovered from the trauma they suffered.

3. Possessive attack

The most obvious manifestation is that the dog refuses to surrender what it has picked up from its owner. When forced to surrender it, it will howl or even bite. Possessive aggression and dominance aggression often occur at the same time, mainly caused by the pet’s "desire to control". 

4. Food attack

The primitive nature of a dog is a very crude behavior of protecting food, roaring while eating, and even biting the owner. Food attacks often occur simultaneously with dominant attacks. Therefore, from an early age, let the dog understand that the owner brought food to it, not the food that was taken away. 

The aggressiveness of dogs is relative. There are only dogs with a more docile personality, and there are no dogs who are absolutely non-aggressive. What I’m talking about here is a dog with a weaker aggressiveness. If you don’t usually annoy it, it won’t attack. The three most non-aggressive dogs known in the world are Labrador, Golden Retriever, and Husky. These three kinds of dogs are not without aggressiveness, but relative, because they have a more docile personality, strong endurance, and better socialization.
