Humans are more intelligent than dogs. When fully developed, a dog has the IQ of a 4 years old human. Why do we often feel that it is easier to train a dog? Dogs don’t make things unnecessarily complicated, but human often do. It is harder for human to change because we dont just think about what is best for the dog, we often let our feeling, emotion and ideology get in the way of rational thinking when it comes to our dogs. A dog does what is best for a dog. People tend to do what makes them feel the best - even if it may not be the best for them nor their dogs.
