Nose not projecting forward.

Eyes
Set wide apart, medium in size, not full, as dark as possible. Slightly sunk in head, sharp and intelligent, which, looking from under heavy eyebrows, impart a piercing look. Light coloured eyes highly undesirable.

Ears
Small, erect and carried firmly, terminating in sharp point, set neither too wide nor too close. Hair short and smooth (velvety), should not be cut. Free from any fringe at top. Round-pointed, broad, large or thick ears or too heavily coated with hair most undesirable.

As broad between canine teeth as is consistent with varminty expression required. Teeth large for large size of dog, with regular scissor bite, i.e. upper teeth closely overlapping lower teeth and set square to the jaws.

Neck
Sufficiently long to allow proper set on of head required, muscular and gradually thickening towards base allowing neck to merge into nicely sloping shoulders.

White.

Height at withers approximately 28 cms (11 ins).

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.

Note
Male animals should have two apparently normal testicles fully descended into the scrotum.
