Here are three smaller-sized herding dogs: Shetland Sheepdog, Cardigan Welsh Corgi, and Pembroke Welsh Corgi.
Miniature in size, much like the ponies for which the relatively barren and rocky Shetland Islands are known, the Sheltie is a little edition of the rough Collie. His body is somewhat long and rounded having a heavy stand-off coat of straight harsh hair, as well as an abundant mane and frill and feathered legs and tail. His head is long and wedge-shaped, tapering a bit from ears to nose, cheeks flat, jaws neat and strong. The ears small and semi-erect, eyes are slanting,
WEIGHT: 18-20 pounds
HEIGHT: 13-16 inches
COLOR: black, blue merle, and sable, marked with white and/or tan.
Welsh Corgi, Cardigan
The Cardigan Welsh Corgi, among the oldest breeds in the British Isles, is a squatty, Dachshund-like dog whose ancestors came to Cardiganshire, Wales, with the Celts from Central Europe about 1200 B.C. Instead of just herding, they nip at the cattle's heels and then drop near the ground when they kick. This is a long, powerful little dog, with deep chest and well-sprung ribs, short legs with rather large and rounded feet, and long tail like that of a fox's
WEIGHT, males 30-38 pounds; females 25-34 pounds
HEIGHT 10 1/2-12 1/2 inches
COLOR: Shades of red, sable, and brindle; black or blue merle with or without tan or brindle points.
Welsh Corgi, Pembroke
The Pembroke Welsh Corgi still ranks as one of dogdom's ancients, its ancestors having been brought in across the Channel to Wales by Flemish weavers in 1107. Later bred in Pembrokeshire from dogs of northern character, the breed has little or no Dachshund traits. The Pembroke Welsh Corgi is a low-set, sturdily made dog, shorter in body than the Cardigan, and having legs that are straighter and lighter in bone. The head is foxy, the muzzle lean, the ears erect with pointed tips. The tail is naturally short or docked.
WEIGHT. 25-30 pounds
HEIGHT 10-12 inches
COLOR: red, sable, fawn, black and tan, with or without white markings.
