A happy dog is a trained dog because it is able to please its owner. Dogs that are irresponsible tend to be miserable because they are always getting into one scuffle or the other much to the dislike of their owners. To make sure that your dog is happy, train it. Don’t spoil your dog by petting it too much. Dogs like kids need a firm hand occasionally to live up to your expectations. A lax attitude in training your dog will leave you with a dog that chooses to do what it pleases.
