GENERAL APPEARANCE - Essentially a working terrier.
CHARACTERISTICS - Capable of following a horse, combining activity with gameness.
TEMPERAMENT - Active and game as previously stated.
HEAD AND SKULL - Head like that of an otter but moderately broad in skull, with short strong muzzle. Black nose preferable, but liver or flesh coloured one not a serious fault.
EYES - Dark with keen expression.
EARS - Small, V-shaped; of moderate thickness, and dropping forward close to the cheek.
MOUTH - Scissor bite, i.e. upper teeth closely overlapping lower teeth and set square to the jaws. Level bite acceptable. Undershot or overshot a major fault and highly undesirable.
NECK - Of moderate length.
FOREQUARTERS - Forelegs straight, not too heavy in bone.
BODY - Deep, narrow, fairly long. Ribs carried well back, but not oversprung, as a terrier should be capable of being spanned by both hands behind the shoulder. Loins strong.
HINDQUARTERS - Racy.
FEET - Small with thick pads.
TAIL - Moderately short; fairly thick at base, then tapering. Set high, carried gaily, but not curled over back.
GAIT/MOVEMENT - Has the soundness to follow a horse.
COAT - Harsh and dense; with close undercoat. Skin must be thick.
COLOUR - Red, wheaten, grizzle and tan or blue and tan.
SIZE - Weight: Dogs 5.9-7.1 kg (13-15 1/2 lbs)
Bitches 5.1-6.4 kg (11.5-14 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 on the terrier's ability to work.
NOTE - Male animals should have two apparently normal testicles fully descended into the scrotum.
