Answer:
One type of person the dog trainer discusses is the "alpha" or dominant person. The advantage of this type of person is that they can establish themselves as the leader of the pack and effectively train their dog. However, the disadvantage is that this approach can sometimes be too forceful and intimidating for the dog, leading to fear and anxiety.
Another type of person the dog trainer discusses is the "permissive" or passive person. The advantage of this type of person is that they are often very patient and gentle with their dog, creating a relaxed and comfortable environment. However, the disadvantage is that the dog may not respect them as a leader and may struggle to follow commands and behave appropriately.
