The AKC has grouped all of the breeds that it registers into seven categories, or groups, roughly based on function and heritage. Breeds are grouped together because they share traits of form and function or a common heritage.
The Rat Terrier was originally bred for ratting and farm work. A multipurpose companion dog that is capable of hunting rodents and vermin above and below ground, and to course small game. He is a sturdy, compact, small-to-medium sized parti-colored dog giving the appearance of elegance and fitness, denoting speed, power and balance. Honorable scars or a couple of broken or missing canines or incisors teeth are not to be faulted. The following is a description of the ideal Rat Terrier. Variations are penalized to the extent of the deviation.
The head resembles a smooth, blunt wedge from a front or profile view. When seen from the front, the head widens gradually towards the base of the ears in an unbroken line and is well filled up under the eyes. The expression is intelligent, alert and full of interest. The eyes are not large. They are obliquely set wide apart and are oval in shape. Eye color varies with coat color from darkest brown to hazel. Eye rim pigmentation corresponds with nose color and facial markings. Gray eyes are acceptable in blue or blue-fawn dogs only, being a serious fault in other colorations. Any blue in the eye(s) is a disqualification.
The body is compact, strong and flexible with well sprung ribs. The brisket extends to the elbow. When viewed from the front, the ribs appear to be oval. The Rat Terrier, while muscled and fit, has flat muscles that blend into the body. The chest is moderately wide and well filled with a discernible forechest. The underline ascends gradually with the ribs extending well back to a moderate tuck-up. Back – The back is level and firm from the withers to the loin. The short loin has a slight muscular arch blending into the gently rounded croup.
The shoulder blades are well laid back with flat muscles providing enough space between the shoulder blades to allow for free movement. The shoulder blades and the upper arms are nearly equal in length and well set back so that the elbows fall directly under the highest point of the shoulder blade. The depth of the body at the elbow is the same distance as from the elbow to the ground. The forelegs stand straight and parallel with elbows turning neither in nor out. The pasterns are slightly sloping when viewed from the side. The feet are oval in shape. The toes turn neither in nor out, are compact, moderately arched, with thick pads and strong nails. The front dewclaws may be removed.
The hindquarters are muscular but smooth and in balance with the forequarters. They should not be bulging or coarse. Stifles are well-bent with short hocks that are parallel and perpendicular to the ground. The hind feet although slightly smaller are similar to the front feet. Rear dewclaws are removed.
Short, close lying, smooth and shiny coat. Texture varies; a very slight ruff or wave along the back is allowed, but undesirable. Any suggestion of kink or curl is cause for disqualification. Whiskers must not be removed. Absence of coat (total genetic hairlessness) is a disqualification.
Balanced, compactly built Rat Terriers are tough but elegant-looking. There are two size divisions: Miniatures stand 10 to 13 inches at the shoulder; standards are over 13 inches and as high as 18 inches. The smooth, shiny coat comes in varieties of pied patterns. (Pied, a word borrowed from the horseman’s lexicon, means “comparatively large patches of one or more colors in combination with white.”) These smoothly muscled exterminators are constructed for the efficient movement required for a long day’s work.
The Rat Terrier should do well on a high-quality dog food, whether commercially manufactured or home-prepared with your veterinarian’s supervision and approval. Any diet should be appropriate to the dog’s age (puppy, adult, or senior). Some dogs are prone to getting overweight, so watch your dog’s calorie consumption and weight level. Treats can be an important aid in training, but giving too many can cause obesity. Learn about which human foods are safe for dogs, and which are not. Check with your vet if you have any concerns about your dog’s weight or diet. Clean, fresh water should be available at all times.
The Rat Terrier’s short, dense coat requires very little care to remain in good condition. A weekly once-over with a soft brush or hound glove will keep his coat healthy and glossy. A bath every month or so will likely be enough, depending on the dog’s lifestyle. Rat Terriers shed seasonally, during which time a shedding tool or rubber curry brush will help remove loose hair. The nails should be trimmed at least monthly, keeping them short and neat, as overly long nails can be painful to the dog. Check his ears weekly, and remove any excess wax and debris, which can cause ear infections. Teeth should be brushed daily if possible, using a toothpaste formulated for dogs.
Some Rat Terriers can get sufficient exercise for their needs through indoor playtime, but most will thrive with daily walks and a bit of tennis-ball-chasing and other play in a fenced enclosure. They tend to do well with other dogs their size or larger. Early socialization is a must, and puppy training classes are recommended. The Rat Terrier has a strong prey drive, and they should never be allowed off lead, as most will not be able to resist the urge to chase when faced with a strange cat or squirrel.
The Rat Terrier is extremely intelligent and trainable, although some can be stubborn and determined at times. They can excel in agility, obedience, rally, and other canine sports. They are unusually sensitive and intuitive, and they love to please their owner—they thrive on praise and respond quickly to positive training methods. Most are patient and tolerant of children but may be reserved with strangers. While they are one of the calmest of the terrier breeds, they are nevertheless high-energy dogs who require exercise, daily walks, and lots of companionship. They are at their best as members of a human family.
Rat Terriers are generally very healthy dogs, and responsible breeders screen their stock for health conditions such as hip dysplasia, patellar luxation (loose kneecaps), Legg-Calve-Perthes disease, and cardiac and eye disorders. A conscientious breeder does genetic testing of all breeding stock with the aim of reducing the incidence of and ultimately eliminating health problems.
