Dogs are much better than children. Think about the stages of a child's life. They are horrible babies who cry all the time and are constantly in danger. Then they are toddlers and they can talk. All they talk about is dumb stuff, or they act awful to you. Then there's a short sweet period. Then they become teenagers. If you've had teenagers then you know that they are the cruelest demographic on the planet, especially to parents. After that they become adults and don't care about you.
Now let's think about a dog. A dog has a difficult time as a puppy, but still very cute. After that the dog constantly loves you. There's no evil teenager period. No wonder this dog took over every single spot in the family photo. The dog is the only family member worthy of that honor.
