Rat Terrier Calendars: Small, powerful, and very intelligent. They are great for sports, utility, or as a companion dog. Very loyal, loving, and protective of their loved ones and possessions, the Rat Terrier is also a great hunter. In fact their original use, hence the name, was for ratting. And if the occasion call, they can be quite the comedian. Rat Terriers are very low maintenance and once you have one...you've got to have another! They are energetic, intelligent and curious. They are game dogs, very tenacious when hunting and affable at home. They are not overly energetic, and tend to have moderate activity. They are very affectionate, playful and desire to be with their people all day. They get along well with their peers, including other pets as well as children. Rat Terriers are small and quaint, but not quite as small as the Chihuahua. They are still rather sturdy little dogs, and somewhat resemble a miniature Jack Russell Terrier. There are several different standards with this breed that vary greatly from country to country. In America, there are Miniature and Standard Rat Terriers, while in other countries they recognize those as well as a Hairless version. Either way, the personality is the same. Rat Terrier Calendars make great gifts.
