When choosing a dog, families should not only evaluate the dog' s ability to interact with other animals, but should also inquire about the dog' s friendliness to unfamiliar people  Dog experts attempt to justify inquiries about a dog' s friendliness to unfamiliar people by saying that this behavior might also mean the dog could adjust well to new children in the family  But such behavior might also show that the dog is an incompetent watchdog
Ttherefore, families looking to choose a dog should not be concerned with the dog' s friendliness to unfamiliar people
A dog might be able to distinguish between children and those people who pose a danger to the family.
