The Smooth Collie is a breed of dog
developed originally for herding. It is a short-coated version of the Rough
Collie of Lassie fame. Some breed organisations consider the smooth-coat and
rough-coat dogs to be variations of the same breed.
Description
Appearance
The
Smooth Collie is a medium-large dog, ranging in size from 20–22 inches (51–56
cm) for females and 22–24 inches (56–61 cm) for males at the shoulder; weights
vary from 40 lb (18 kg) for females up to 66 lb (30 kg) for males. Standard
size for the breed is in the United States and Canada 22–24 inches (56–61 cm)
for females and 24–26 inches (61–66 cm) for males at the shoulder; for example,
for the AKC, the range is 22–26 inches (56–66 cm) and 50–75 lb (23–34 kg).
The Smooth
Collie is slightly longer than it is tall, with a level back and a deep chest.
The features of the head, particularly the "sweet" expression, are
considered very important in the show ring. The breed has a long muzzle, flat
skull, and semi-erect ears (although, in practice, the ears typically must be
folded over and taped in puppyhood, or they will usually be fully upright in
the adult dog).
Coat
The
coat consists of a soft, extremely dense undercoat and straight, harsh outer
guard hairs. The guard hairs are one to two inches long, with the longer hair
mainly in a ruff around the neck and on the backs of the thighs. The coat
requires a thorough weekly brushing. Shedding is moderate most of the year,
heavy during the twice-yearly shedding season.
Colour
Smooth
Collies come in four colours: sable ; tricolour (black, with tan and white
markings); and blue merle (silvery gray marbled with black, and tan markings),
all marked with white areas on the chest, neck, feet/legs, and tail tip. An
additional colour is white (these Collies are predominantly white, with heads
and usually a body spot of sable, tri, or blue colour). The fourth colour is
sable merle, which is a light stippled version of sable, sometimes (as with
blue merle) accompanied by blue or merled (parti-coloured) eyes. Blue eyes or
merled eyes in a non-blue merle collie are not disqualifications in the AKC
standard although they are heavily penalised. There are, however, plenty of
blue-eyed or merled-eyed sable merle collies who are AKC breed champions.
Temperament
Health
The
Smooth Collie is a long-lived breed for its size, usually living 12 to 14
years. Like all dog breeds, they are susceptible to certain inherited or
partially inherited health problems. Those problems currently include:
·
Collie eye anomaly (CEA): A collection of eye
problems ranging from minor blood vessel abnormalities to blind spots to
severely deformed or detached retinas. This problem is so widespread in collies
that completely unaffected dogs (called "normal eyed") are uncommon,
although conscientious breeders have been able to gradually increase the normal
population. The problem and its extent can be determined through an eye exam
conducted before six weeks of age, and does not get worse over time. Mildly
affected dogs suffer no impairments, and are fine pets or working dogs.
·
Progressive retinal atrophy: Gradual
degeneration of the retinas of the eyes, eventually leading to blindness. This
disease is less common than CEA in Collies, but more difficult to breed away
from, as symptoms are not usually detectable until the affected dog is
middle-aged or older.
·
Multidrug sensitivity: Sometimes fatal reactions
to a class of common drugs, particularly ivermectin, used as a heartworm
preventative and treatment for mites. The gene that causes this sensitivity has
recently been identified, and a dog's susceptibility can now be determined
through a simple blood test.
·
Gastric dilatation volvulus (bloat): A painful
and often fatal twisting of the stomach occurring in large or deep-chested
breeds which can usually be prevented by feeding small meals and not allowing
vigorous exercise immediately before or after eating.
·
Epilepsy: Seizures of unknown origin. Frequency
of the seizures can often be significantly reduced through medication, but
there is no cure for this disease.
·
Cyclic Neutropenia: CN is also known as Gray
Collie Syndrome. Cyclic Neutropenia is a disease that affects the neutrophils
of a dog, which are an integral part of the dog's immune system. Most affected
dogs will die as puppies, and even with the best care, the dog will not likely
live past 2–3 years of age.
Smooth
Collies can compete in dog agility trials, obedience, showmanship, flyball,
tracking, and herding events. Herding instincts and trainability can be
measured at noncompetitive herding tests. Collies exhibiting basic herding
instincts can be trained to compete in herding trials.
