"Drury, W.D., British Dogs, Vol. 1; The 3rd Edition. Here in full is the 1901 Description by Mr. Lionel Jacobs, of the "Lhassa Terrier, an interesting little breed formerly found under the inappropriate name of Bhuteer Terrier."

Head.  Distinctly Terrierlike. Skull narrow, falling away behind the eyes in a marked degree, not quite flat, but not domed or apple shaped. Fore face of fair length, strong in front of the eyes, the nose, large, prominent and pointed, not depressed; a square muzzle is objectionable. The stop, size for size, about that of a Skye Terrier.

Mouth.  Quite level, but of the two a slightly overshot mouth is preferable to an undershot one. The teeth are somewhat smaller than would be expected in a Terrier of the size. In this respect, the breed seems to suffer to an extraordinary degree from cankered teeth. I have never yet seen an imported specimen with a sound mouth.

Ears.  Set on low, and carried close to the cheeks, similar to the ears of a dropeared Skye.

Eyes.  Neither very large and full nor very small and sunk, dark brown in colour.

Legs and Feet.  The fore legs should be straight. In all short legged breeds there is a tendency to crookedness, but the straighter the legs the better. There should be good bone. Owing to the heavy coat the legs look, and should look, very heavy in bone, but in reality, the bone is not heavy. It should be round and of good strength right down to the toes, the less ankle the better. The hocks should be particularly well let down. Feet should be round and catlike, with good pads.

Body.  There is a tendency in England to look for a level top and a short back. All the best specimens have a slight arch at the loin and the back should not be too short; it should be considerably longer than the height at the withers. The dog should be well ribbed up, with a strong loin and well developed quarters and thighs.

Stern.  Should be carried well over the back after the manner of the tail of the Chow. All Thibetan dogs carry their tails in this way, and a low carriage of stern is a sign of impure blood.

Coat.  Should be heavy, of good length and very dense. There should be a strong growth on the skull, falling on both sides. The legs should be well clothed right down to the toes. On the body, the hair should not reach to the ground, as in a show Yorkshire; there should be a certain amount of daylight. In general appearance the hair should convey the idea of being much harder to the eye than it is to the touch. It should look hard, straight and strong, when to the touch it is soft, but not silky. The hair should be straight with no tendency to curl.

Colour. Black, dark grizzle, slate, sandy, or an admixture of these colours with white.

Size.  About l0 in. or 11 in. height at shoulder for dogs, and 9 in. or l0 in. for bitches."
