Dogs can be irritable, less than polite, and sharply argumentative if you cross any dearly-held principle. They also can be worriers, even on the alert to protect their families and those they love.
One's first impression is of an easygoing and friendly person with a casual, comfortable beauty. This is true. They can be stubborn, and make snap judgments, but this may not be obvious at first. Dogs like outdoor activities and having fun with friends. They are cooperative and easy going much of the time.
Dogs make wonderfully loyal friends. Straightforward and direct, they value personal integrity and have a strong sense of responsibility. A Dog can be surprisingly judgmental. People are either with them or against them. Like guard dogs protecting their home, Dogs are alert to assess new people. They are naturally suspicious. A Dog makes friends slowly. They will protect a friend's interests as if they were their own.
