Sealyham Terrier Breed Standard

This breed standard was last updated September 2007 and has been taken from the Kennel Club Website and adapted for this website.​

A Breed Standard is the guideline which describes the ideal characteristics, temperament and appearance including the correct colour of a breed and ensures that the breed is fit for function. Absolute soundness is essential. Breeders and judges should at all times be careful to avoid obvious conditions or exaggerations which would be detrimental in any way to the health, welfare or soundness of this breed. If a feature or quality is desirable it should only be present in the right measure.

​However, if a dog possesses a feature, characteristic or colour described as undesirable or highly undesirable it is strongly recommended that it should not be rewarded in the show ring.

General Appearance
Free-moving, active, balanced and of great substance in small compass. General outline oblong, not square.

Alert and fearless but of friendly disposition.

Neck
Fairly long, thick and muscular on well laid shoulders.
 
Forequarters
Forelegs short, strong and as straight as possible consistent with chest being well let down. Point of shoulder in line with point of elbow which should be close to side of chest.

Notably powerful for size of dog. Thighs deep and muscular with well bent stifle. Hocks strong, well bent and parallel to each other.
 
Feet
Round and cat-like with thick pads. Feet pointing directly forward.
 
Tail
Previously customarily docked.
Docked: Medium length. Thick with a rounded tip. Set in line with back and carried erect. Quarters should protrude beyond set of tail.
Undocked: Medium length of tail to give a general balance to the dog. Thick at root and tapering towards tip. Ideally carried erect, but not excessively over the back, and with no curl or twist. Quarters should protrude beyond set of tail.

Size
Height should not exceed 31 cms (12 ins) at shoulder. Ideal weight: dogs approximately 9 kgs (20 lbs); bitches approximately 8 kgs (18 lbs). General conformation, overall balance, type and substance are main criteria.

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 and on the dog’s ability to perform its traditional work.

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

Notes for prospective puppy buyers
Size – the Kennel Club Breed Standard is a guide and description of the ideal for the breed, the Size as described does not imply that a dog will match the measurements given (height or weight). A dog might be larger or smaller than the Size measurements stated in the Breed Standard.
