Despite its name, the roots of the American Eskimo dog can be traced back to Germany where it was known as a white colored, miniature to medium sized variety of the German spitz. This well rounded farm dog came to the United States with German immigrants in the early 20^th century and adopted the name American spitz in the World War I era when war related anti-German sentiment and American patriotism were widespread. The breed was first recognized as the American Eskimo dog (AED) by the United Kennel Club in 1919 and was accepted by the American Kennel Club for registration in 1995. Known for its alert demeanor, the AED makes an excellent watchdog that alarms its family of potential danger through warning barks. The AEDs intelligence, fast learning, and desire to please have made it a competitor in the agility ring and obedience trials. Though not universally recognized as three separate varieties, the modern AED is often split into three size groups (toy, miniature, and standard).

Despite its many talents, beautiful physical characteristics, and intelligence, like other pure breeds, the AED has developed some inherited disease concerns over the course of its development that have caused significant issues ...

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 ...

In this fourth and final blog in a series about preventable inherited diseases in the Labrador retriever (see previous blogs here; part one, part two, and part three), we will examine a potentially life-threating urinary disease and a cause of blindness in dozens of dog breeds including the Labrador.

Cystinuria

Urinary tract obstruction is one of the most urgent and potentially life-threatening conditions in dogs. One common cause of urinary obstructions in dogs is the presence of bladder stones which leave the bladder during urination and become lodged in the urethra. The inability to urinate results in a toxic buildup of certain electrolytes and waste products in the body including potassium, which tends to be the most concerning in regards to health effects. Excess potassium in the body prevents the heart from beating normally, ultimately resulting in death due to cardiac arrest. Though it is not the only cause of bladder stones in Labradors, a genetic mutation in the SLC3A1 gene is reported to cause an early-onset disease known as cystinuria, which can result in bladder stone formation.

While normal kidneys reabsorb a variety of nutrients and electrolytes from the urine, dogs affected with cystinuria lack the ability to produce ...

With their picturesque appeal, predecessors of the modern day papillon (known as continental toy or Titian spaniels) were popular subjects for European painters between the 16^th and 18^th centuries. The popularity of these small spaniels with European aristocrats and royalty of the Renaissance period, led to their appearance in many paintings from the era. The iconic, longhaired “butterfly-like” ears, for which papillons are named, are obvious in these paintings though many of the portrayed dogs were of the drop-eared variety of the breed that today is known as the phalène. According to an article on the Papillon Club of America website, in the late 19^th century erect ears became a more desirable trait with papillon fanciers and eventually the erect-eared variety obtained their current position as the more popular form of the breed. In addition to their beautiful physical attributes, in their modern form, well-socialized papillons are described as happy, playful and affectionate family members. Papillons are also often described as frequent barkers, making them great guard dogs. Despite their adorable personalities and good temperament, like other purebred dogs, the papillon is known to inherit some genetic diseases that could prevent this regal breed from reaching the ...
