The Border Collie is a medium sized, energetic working dog. Its body is slightly longer than it is tall. The relatively flat skull is moderate in width. The skull and muzzle are about the same length, with a moderate stop. The oval eyes are set well apart and brown in color, except in merles where one or both eyes may be blue. The medium sized ears are set well apart, either carried erect or semi-erect. The front legs are straight when viewed from the front, but slightly sloping when viewed from the side. The medium sized tail is set low reaching at least to the hock, rising somewhat when the dog is excited. Dewclaws are usually removed. The double coat is weather resistant, dense and close-fitting. There are two coat varieties: a short, sleek coat (about 1 inch (2.5 cm) long) and a coarse, rough coat (about 3 inches (7.6 cm) long). The coat colors come in black and white, tricolor, red and white, black and gray, yellow, yellow and white, sable, and other color varieties including merles (see chart below). The longer haired variety should have a mane and tail brush. The hair on the face, ears and front legs is always short and sleek. Since Border Collies are bred for working ability and intelligence rather than for physical beauty, conformation varies widely.

Coat Colors

Tempermant
The Border Collie is very intelligent and aware of its surroundings. It is able to be trained to a high degree. This is one of the hardest working dogs thriving on praise. Border Collies are represented among the leaders in competitive levels in various sports, excelling in agility skills, obedience, sheepdog trials and Frisbeeā„¢. These competitions are right up their alley, and they are commonly used and often win. For those who wish to reach high levels in dog sports, the Border Collie is a gift from heaven. Farmers are also happy with them, as they were originally bred as a farmhand. The Border Collie is highly energetic with great stamina. Provided they get sufficient activity to keep them occupied and ample exercise, the Border Collie will get along quite happily with other dogs and children, however they may be aggressive with other dogs of the same sex if you are not showing 100% leadership with them. They should not be trusted with small non-canine pets, however there are plenty of Border Collies that live and get along with family cats. This breed can be sensitive and should be very well socialized as a puppy to prevent shyness. To be truly happy, they need a lot of consistent leadership, extensive daily exercise, and a job to occupy their minds. Border Collies will often challenge their owners' authority when they are adolescents. Dominance levels vary greatly, even within the same litter. You need to be this dog's firm, confident, consistent pack leader, or he may try and take over. If you allow him to take over, without enough socialization and mental and physical exercise, he can be highly reactive and sound sensitive, making him a poor choice for families with young children. The Border Collie is a perfectionist with a permanent will to please. This breed lives for serving you day in and day out. It is not an ideal pet for people who do not plan to spend a lot of time with it. These dogs are too intelligent to lie around the house all day with nothing to do. If you are not willing to put many hours a day into keeping these dogs well exercised in both mind and body, then it is recommended you do not adopt a Border Collie. There are other breeds that are similar yet not as demanding. If there is insufficient activity then it will find its own work to do, and that may not be what YOU had in mind when we say the word WORK. When not challenged daily they can and will become destructive. They cannot be left alone for too long with nothing to do if they have not been exercised to the point where they are both mentally and physically tired. A bored Border Collie will not make a good pet, as it can become neurotic and may start using its escape artist talents, among other behavior problems. They have strong herding instincts and may try to herd children and strangers and must be told this is not acceptable.

Living Arrangements
The Border Collie is not recommended for apartment life. They are very active indoors and do best with acreage. This breed will do fine in a kennel provided it has daily activity and sees plenty of its handler. This breed is not suited to life chained up in the backyard all day.

Exercise
Physical exercise alone is not sufficient for this very intelligent and highly energetic dog. They want to work and must do so with body and mind as one, carrying out different tasks. Fast and agile, these lively little dogs have boundless energy and thrive on hard work and play. They should also be taken on a long, brisk daily walk. They are a delight to see streaking after a ball or bringing straying sheep back to the fold.

Grooming
The Border Collie needs regular combing and brushing to keep the coat gleaming. Extra care is needed when the soft, dense undercoat is shedding. Bathe or dry shampoo only when necessary. Check the ears and coat regularly for ticks. This breed is an average shedder.
