The collie is a type of herding dog, including several related land races and formal kinds. The breed originated from Scotland and Northern England. Collie breeds have spread through several areas of the world (Especially Australia and The United States) and have varied into many options, sometimes with blend from different dog breeds. Some breeds have stayed as working dogs, for herding lamb and cows as well as livestock, while some are maintained as exhibit dogs, pets or for dog sports, in which they present train-ability, stamina and agility. Popular use of the brand “collie” in some parts is bound largely to certain varieties – including for the Rough Collie in areas of the United States, or to the Border Collie in several rural parts of Great Britain. Many collie sorts do not actually incorporate “collie” inside their brand.

Physical Appearance

Collies are usually medium sized dogs of approximately 22 to 32 kilogram (48 to 70 pound) and light to medium-boned. Cattle- types that are herding are tend to be stockier.  The fur might be flat, long, or short, while the tail may be bushy, feathered out, or smooth. Collies can have either naturally bobbed or naturally long tails, or some of the breed clubs will actually dock the tail.  The tail may twist high over the back or it may be presented low with an upward swirl. It however, does not ever curl at the base, nor does it touch the back. Each type can vary in coloration, with all the normal starting colors being black, black-and- red, red-and- tan. They often times have white combined with the key color, generally beneath the abdomen and chest, over the shoulders, and on elements of the face area and thighs, but occasionally causing only the head to be colored – or white could possibly be absent or limited to the chest and feet (as within the Australian Kelpie). Merle coloration are often current over some of the color combinations that are different in land race sorts. The most common and widespread patterns of the Collie include, black-and-white, tricolor, and sable.


An operating or working member such as the Border Collie, can be an exceptionally lively and agile dog with great stamina. If the dog is in fit condition, it can run all day without becoming tired, even over rough or steep grounds. Working collies present a keen intellect for the task at hand and therefore are naturally very motivated. They are usually extremely loyal. All collie dog breeds have proved to be extremely trainable, mild, loyal, smart, and suitable as pets. Their gentleness also ensures they are very compatible with children. Although the different personalities of the dogs differ they’re typically more desirable as watchdogs than as guard dogs.


Some collie breeds (particularly the Rough Collie along with the Smooth Collie) are affected by a genetic problem, a mutation inside the MDR1 gene. Affected pets are extremely sensitive with a medications, including Ivermectin, together with some antibiotics, opioids and steroids – more than 100 drugs as a whole. Affected pets also display less cortisol concentration than standard.

Collies may have canine cyclic neutropenia, a genetic disease, or Grey Collie Syndrome, which is a stem cell disorder. Puppies with this disorder are quite often mistaken for healthy Blue Merles, though their color is a silver-grey. For more than 6 months, affected puppies seldom live. For a dog to be affected, both the dam along with the sire need to be carriers of the disorder.
