Breed standardFox Terrier (Smooth)

General Appearance	Active and lively, bone and strength in small compass, never cloddy or coarse. Neither leggy nor too short in the leg, standing like a well made, short-backed hunter, covering a lot of ground.
Characteristics	Alert, quick of movement, keen of expression, on tiptoe of expectation.
Temperament	Friendly, forthcoming and fearless.
Head and Skull	Skull flat, moderately narrow, gradually decreasing in width to eyes. A little stop apparent, cheeks never full, jaws, upper and lower, strong and muscular, falling away only slightly below eyes. This portion of foreface moderately chiselled out, so as not to go down in a straight line like a wedge. Nose black.
Eyes	Dark, moderately small, as near as possible circular in shape but not prominent. Expression bright and intelligent.
Ears	Small, V-shaped and dropping forward close to cheek, not hanging by side of head. Fold of ear above level of skull. Leather of moderate thickness.
Mouth	Jaws strong with a perfect, regular and complete scissor bite, i.e. upper teeth closely overlapping lower teeth and set square to the jaws.
Neck	Clean and muscular, without throatiness, of fair length and gradually widening to shoulders.
Forequarters	Shoulders long and sloping, well laid back, fine at points, cleanly cut at withers. Legs from any angle must be straight showing little or no appearance of an ankle in front. They should be strong in bone throughout.
Body	Chest deep, not broad. Back short, level and strong without slackness. Loin powerful, very slightly arched. Foreribs moderately sprung, back ribs deep.
Hindquarters	Strong and muscular, quite free from droop or crouch; thighs long and powerful, hocks well let down, good turn of stifle.
Feet	Small, round and compact. Soles hard and tough, toes moderately arched, and turning neither in nor out.
Tail	Previously customarily docked. Docked: Set on rather high and carried gaily but not over back or curled. Of good strength. Undocked: Set on rather high and carried gaily but not over back. As straight as possible. Tail of moderate length to give balance to the dog.
Gait/Movement	Fore- and hindlegs carried straight forward and parallel. Elbows move perpendicular to body, working free of sides, stifles neither turning in nor out and hocks not close. Good drive coming from well flexing hindquarters.
Coat	Straight, flat, smooth, hard, dense and abundant. Belly and underside of thighs not bare.
Colour	White should predominate, all white, white with tan, black and tan or black markings. Brindle, red or liver markings highly undesirable.
Size	Dogs: 7.5-8 kgs (16-18 lbs); bitches: 7-7.5 kgs (15-17 lbs).
Faults	Any departure from the foregoing points should be considered a fault and the seriousness with which the fault should be regarded should be in exact proportion to its degree and its effect upon the health and welfare of the dog.
Notes	Male animals should have two apparently normal testicles fully descended into the scrotum.
