Prevention Is Smart Breeding- Collie Eye Anomaly and the Australian Shepherd

Prevention Is Smart Breeding- Collie Eye Anomaly and the Australian Shepherd

Despite a name which implies an origin “down under”, the Australian shepherd is widely understood to be a breed of American origin. In fact, descriptions of the breed and their importance in the lives of 19th and 20th century Basque shepherds who had relocated from Australia to the western US are plentiful. Australian shepherds’ exceptional intelligence, versatility, desire to please, and a natural instinct to herd and guard livestock have made them a common inhabitant of ranches and farms where they have been trained to perform a variety of tasks. Aside from their work on the homestead, their unique abilities have also made them great competitors in stock dog trials, agility events, and other dog sports. Despite their many talents and desirable traits, like many other breeds, the Australian shepherd has developed some inherited disease concerns that can prevent them from performing at their best or otherwise decrease their overall quality of life. One such condition recognized in the Australian shepherd is the genetic eye disease known as collie eye anomaly.

Preventing Inherited Progressive Retinal Atrophy in the Irish Setter

Preventing Inherited Progressive Retinal Atrophy in the Irish Setter

Despite its once prominent role as a talented upland gamebird hunting dog, by the mid-1900s the Irish Setter’s popularity in the field was on the decline. Despite developing significant interest and success as a show dog, the breed had nearly disappeared from the hip of gamebird hunters. Around this time, outbreedings to field champion English setters were performed in an effort to resurrect the popularity and improve the talents of the Irish setter as a hunting companion. In many locales, this field bred variety of Irish setter became known as the red setter while the Irish setter name is now most closely associated with the show variety of the breed. In the United States however, red setters still fall under the umbrella of the Irish setter name. Found in multiple colors and coat patterns in its early history, the breed’s modern solid red coat color became entrenched in the breed due to its popularity in the European show ring of the late 1800s.

Like other purebred dogs, the Irish setter has developed some inherited disease concerns along its path to its modern state. However, through the use of modern genetic testing technology and selective breeding practices, some inherited diseases can now be ...

Preventing Inherited Congenital Stationary Night Blindness in the Briard

Preventing Inherited Congenital Stationary Night Blindness in the Briard

With depictions in artwork from as early as the 8th century, the ancient Briard is a French dog breed that has been employed in diverse roles throughout its history, but is most commonly recognized as a herding breed or as a guard dog for flocks of sheep. Though documentation of its early history is sparse, the first breed standard for the Briard was written in the late 19th century and the breed was accepted for registration by the AKC in 1922 after being brought to North America from Europe (including Briards imported by Thomas Jefferson). Praised for their intelligence and memory, the Briard is a naturally protective dog that can benefit from early and extensive socialization in order to establish proper boundaries and temperament toward strangers. They are often regarded as extremely loyal and bonded to their owners and appreciate significant time with their human “pack”. Though the breed is regarded as relatively healthy, as with most purebred dogs, the Briard has developed some inherited disease concerns during its path to the modern state of the breed. One of the best known Briard inherited disease concerns, unique to the breed, is a disease known as congenital stationary night ...
