Dogs and kids can be best friends. Dogs are proven to have high levels of emotional intelligence, being able to express empathy especially towards small kids in scientific studies. Also, dogs are among the smartest animals when it comes to understanding how civilized society works and dangers while playing, so they can be an excellent choice for kids.
