A hunter made with wit stands solidly on its four legs, the perfect image of physical condition, resistance and strength: the Smooth Fox Terrier embodies the active Terrier with fire in the eyes. 
Fast, resistant and powerful is a good description for the Fox Terrier, which should incorporate the Foxhound’s symmetry. The Smooth Fox Terrier should have a smooth, but rough, thick and abundant coat. It should never be tall on the limbs, or short, able to cover plenty of terrain, and preferably with a short back. Its weight in males is 7.3 to 8.2 kg, and for females 6.8 to 7.7 kg, although the weigh is not representative for the Terrier’s physical condition. The head is flat and somewhat narrow, not too much stop, gradually narrowing from the eyes to the nose. Not full cheekbones. The nose is black, not white, not cherry or spotted. The eyes are dark, small, as round as possible, deep insertion in the socket and full of spark, never in rose, tulip, or risen. The neck is clean and without dewlap; the chest deep, not wide; deep ribcage and not flat; the shoulders long and sloped, elbows closed; straight forelegs; round and compact feet, not large. The hindquarters give the movement potency and should be strong and muscular, with good leg length and good angulations. The white should always be predominant in the coat; it can be completely white, or white with tan, black and tan, or black. The brindle, red or brown (liver) are unacceptable.
Perhaps from every breed, the Fox Terrier is for everyone… almost. It is a small, robust, clean dog, with a lot of spirit and personality that fits in many lifestyles if given the opportunity. It is easy to teach, easy to care for and easy to love. The Fox Terrier needs due socialization to soften its Terrier heart. It likes to bark, and should express its digging talent. A firm scolding is all the Fox Terrier needs to understand your wishes.
The Fox Terrier weighs between 1.5 and 2 kg after eight weeks.
It obeys immediately and is attentive: life with a Fox Terrier is easy. 
Physical maturity is reached at 18 to 24 months. The tail and dewclaws are removed after the first week. The tail docking is important and should be performed by an experienced person. A third of the tail is usually docked, at countries where allowed, if not, it is left natural. The future owner should choose a puppy with a good head, long and clean, without protruding bones, especially behind the eyes (prominent cheekbones). The limbs should be parallel, the feet small and tight, with well arched fingers.
Avoid puppies with fingers turned in or out, as well as closed hindquarters. The ears usually rise during dentition. Correct ears and bit can’t be guaranteed before seven months. Typical Terrier, the adolescent dog usually tests its owner’s authority. The key is firmness and consistency.
A finding for your family lair: the Smooth Fox Terrier puppy should be kind and active, adding a happy note to anyone’s life.
The Fox Terrier is a resistant and extremely well built dog with longevity over 12 year. Although it’s not a troublesome breed, eye and bone anomalies affect it. Retinal luxation, distichiasis and cataracts have been documented in the breed. The few bone problems (hip dysplasia is rare) include shoulder dislocation and Legg-Perthes, which also affects other Terriers and implies deterioration in the femur head, causing progressive limping. Less frequent are deafness, gout, sub aortic stenosis, pulmonary stenosis, recessive ataxia (which manifests at two to four months, a spine defect that causes uncoordination that can escalate to paralysis). Myasthenia gravis is a muscular disease that seems associated with an esophagus elongation in the Smooth Fox Terrier. Hair care is minimal, a little more than passing a brush through a few times per week.
Ideal as a domestic dog for inexperienced people, the Smooth Fox is an inoccus choice for the user.
