History and origin

The FCI standard says that the Fox Terrier, in both its varieties, smooth and wire, is of British origin and probably descends from the same types of dog that produced the Bull Terrier and the black and tan terrier (today's Manchester Terrier). Uniformity of type was fixed in the late 19th century, and the first standard was written in 1876.

Wikipedia says the breed has been known in England since at least the 18th century: the first evidence is a portrait painted in 1790 of Colonel Thornton's dog, Pitch. It was the first breed of the Fox Terrier family recognised by the Kennel Club, around 1875, and many of today's terriers descend from it.

Physical characteristics

The standard describes it as active and lively, with bone and strength “in a small compass”, never cloddy, neither too high nor too low on the leg, standing like a well-made hunter, with a short back. The AKC says that, apart from the coat, it differs from the wire variety in having a more V-shaped head.

General appearance

The coat is straight, flat, smooth, hard, dense and abundant. The belly and the underside of the thighs are not bare.

Feature Smooth Fox Terrier
Size Small
Height at the withers at most 39 cm
Weight 7–8 kg
Coat Short, harsh
Colour White with patches
Type Terrier

White should predominate: all white, white with tan, with black and tan or with black patches. Brindle, red or liver patches are undesirable.

Training and socialisation

The standard describes it as alert, quick, with a keen expression, friendly, forthcoming and fearless. The AKC says it is bold but not aggressive with people, an excellent watchdog, lively and cheerful.

The AKC warns that its digging instinct can damage the garden or flower beds unless it is taught otherwise, and that it should never be let off the lead, as it will go after any small animal.

Tips for effective training

  • Do not let it off the lead. The AKC says it goes after animals.
  • Teach it not to dig. Its terrier instinct is strong.
  • Be consistent. It has a strong personality.
  • Keep it busy. It gets bored quickly.

Activity needs and lifestyle

The AKC says that, like most terriers, it is lively, athletic and needs plenty of exercise: long walks, chasing a ball in the garden or playing in a large, securely fenced area.

Activity How often Why it matters
Long walks daily Fitness
Ball games daily Energy
Search games several times a week Terrier instinct

Tips for a balanced life

  • The fence must be sunk into the ground.
  • Keep it on a lead in the street.
  • Teach it to be quiet from an early age.

Care and health

Coat and skin care

The AKC says the short, hard, dense coat is groomed weekly with a stiff brush or a mitt, and a bath once a month is enough, unless it has dug itself a hole in the mud.

Common health problems

The AKC says the Smooth Fox Terrier is generally healthy, and responsible breeders check their dogs for:

Condition Description Common symptoms
Heart disease Disorders of the heart Tiredness, coughing, laboured breathing
Patellar luxation The kneecap slips out of place Suddenly holds a hind leg up for a few steps, then uses it again

Other care

  • Ask for the parents' health tests.
  • Brush its teeth often.
  • Go for yearly check-ups.

Diet and nutrition

The AKC recommends good-quality food suited to the dog's age, and attention to its weight.

Tips for a healthy diet

The table gives a starting estimate, calculated with the formula from the Merck Veterinary Manual. The first two calorie columns show the calories per day for a healthy adult dog. The last column shows what this means in dry food with 3,500–4,000 kcal per kilogram.

Dog's weight Calories per day (neutered) Calories per day (not neutered) Dry food per day (approximate)
7 kg 480 kcal 540 kcal 120–150 g
7.5 kg 510 kcal 570 kcal 130–160 g
8 kg 530 kcal 600 kcal 130–170 g
  • Treats count towards the daily portion.
  • Split the food into two meals a day.
  • A dog is at the right weight when you can feel its ribs without pressing hard.

Foods to avoid

Some human foods are dangerous for dogs: chocolate, coffee, grapes and raisins, onions, garlic, xylitol (a sweetener used in chewing gum), macadamia nuts and alcohol.

Reproduction and development

Physical and emotional maturity

In dogs, sexual maturity usually comes between 6 and 12 months. Small breeds become adults faster than large ones, usually at around one year.

Mating and pregnancy

Pregnancy lasts about 63 days, counted from ovulation. Mating a female on her first heat is not recommended. The FCI standard requires that only healthy dogs of typical breed appearance are used for breeding.

Caring for the puppies

In small breeds, a litter has 3–4 puppies on average. The puppies are very small and fragile in the first weeks, so they must be kept warm and handled with care. Socialisation starts early: gentle handling, everyday noises and new people.
