Reasons for dogs to attack people:

1. Without the owner’s consent, you entered the area it was guarding, or took away the owner’s things in the area it was guarding.

2. Your behavior is suspicious and you did not enter the owner’s house or room in a normal way.

3. Dogs are very loyal and protective pets. When the owner is threatened or hurt, it is easy to anger the dog and make it attack people.

4. You made excessive jokes with it, bullied it maliciously, or held items that it considered a threat to it, or you have hurt it.

5. You suddenly disturb your dog while it is eating or sleeping.

6. When a dog is nervous and scared, he will subconsciously attack creatures that are close to him and may pose a threat to him.

7. Dogs are particularly sensitive during pregnancy, especially when feeding puppies. It is best not to disturb them.

8. Some dogs are very possessive. If they feel that their owner has been taken away by another person and they are not loved, they may attack that person.
