How To Tell If Border Collie Is Pure Bred


Border Collies are highly intelligent and energetic dogs that have become popular pets and working dogs around the world. If you are considering getting a Border Collie, you might be wondering how to determine if a dog is purebred. While it can be challenging to ascertain a dog’s lineage with absolute certainty without proper documentation, there are several visual cues and characteristics that can provide an indication of whether a Border Collie is purebred.


One of the first things to look for in determining if a Border Collie is purebred is its appearance. Border Collies typically have a medium-sized, well-proportioned body with a strong and athletic build. Their head is relatively broad and wedge-shaped, with a defined stop. They have oval-shaped eyes that are usually brown, although blue or merle eyes can occur in some purebred Border Collies. The ears are medium-sized and usually erect or semi-erect, positioned on the sides of the head. The coat is double-layered, with a dense and weather-resistant outer coat and a soft undercoat. Border Collies come in various coat colors and patterns, including black and white, tricolor, red and white, and blue merle.

Temperament and Behavior

Border Collies are known for their high intelligence, intense herding instincts, and boundless energy. They are highly trainable and excel in various dog sports and activities. A purebred Border Collie should exhibit these characteristic traits. They are typically alert, focused, and always ready for action. They have a strong herding instinct and may try to herd people or objects by nipping at their heels. Border Collies are also highly affectionate and thrive on human companionship. They are generally good-natured and friendly, but can be reserved with strangers. If a dog displays these behavioral characteristics, it is likely that it is a purebred Border Collie.

Pedigree and Documentation

While visual cues and temperament can provide a good indication of a dog’s purity, the most reliable way to determine if a Border Collie is purebred is through proper documentation and pedigree. A purebred Border Collie should come with registration papers from a reputable kennel club, such as the American Kennel Club (AKC) or the United Kennel Club (UKC). These papers provide information about the dog’s lineage, including the names of its parents and ancestors. It is essential to obtain these documents from a reputable breeder and ensure they are legitimate and accurate.

Genetic Testing

For those who want to be absolutely certain about a dog’s breed, genetic testing can be an option. DNA tests designed for dogs can determine the breed composition of a mixed-breed or confirm the purity of a purebred dog. These tests analyze the dog’s DNA and compare it to a database of known breed markers. Some companies even offer specific tests for Border Collies. However, it is important to note that genetic testing can be expensive and may not be necessary if there are sufficient visual cues and documentation available.


Determining if a Border Collie is purebred can be challenging without proper documentation, but there are several visual cues and traits that can indicate its lineage. By examining its appearance, temperament, and behavior, and obtaining proper documentation from a reputable breeder, you can have a reasonable assurance of a Border Collie’s purity. Genetic testing can also provide definitive answers but may not be necessary in all cases. If you are in doubt, consult with a veterinarian or a breed expert for further assistance.
