From its early history as a North American working dog used to retrieve fishing nets and perform human water rescues, the beautiful and intelligent Newfoundland dog has carved out a well-deserved place in the heart of dog lovers around the world. Their characteristic large size, marked by heavy bones, powerful musculature, webbed feet, and thick hair coat make the Newfoundland particularly adept at tasks involving swimming. However, they are just as capable and content pulling carts on land and performing other land-based tasks. In addition, their generally calm, loyal, and affable temperament have helped establish them as great family dogs.  

Over the years, Newfoundland breeders have selectively bred dogs that have displayed the most desirable characteristics in an effort to improve their breed. Unfortunately, alongside these desirable traits, sometimes the predisposition to produce offspring with certain inherited diseases are also silently passed from generation to generation in the form of genetic mutations. Such a genetic mutation found in the canine SLC3A1 gene (first described in 2000) is responsible for a potentially life-threatening condition in the Newfoundland known as cystinuria. Luckily for Newfoundlands and those that love them, cystinuria can be eliminated from most blood lines through the incorporation of ...

From a thorough mixture of spaniels, pointers, and other setter breeds, the Irish setter made its rise to popular gun dog status in the 18^th century in its native homeland, Ireland. Though originally of the red and white color pattern (now called the Irish red and white setter), by the time the Irish setter made its way to North America, the solid red color most commonly associated with the breed had been established through selective breeding practices. Originally bred for their versatility in hunting game birds, by the mid 1900’s the Irish setter’s role in the field had greatly diminished despite their popularity in the show ring. Controversial, yet successful, efforts were taken to outcross the breed to red and white champion English setters in order to preserve and improve field varieties. The resultant field variety, often referred to as the Red setter, is unique in its hunting abilities and appearance when compared to American show varieties of the Irish setter. However, the field variety still falls under the Irish setter name in the US.

Unfortunately, at some point during the breed’s development, a spontaneous mutation in the ITGB2 gene occurred in a single Irish setter. A portion of ...

It is no secret among many Dalmatian owners and their breeders that their beautiful breed is prone to developing bladder stones (uroliths) made of urates as they have historically been the poster puppies for the inherited condition, known as hyperuricosuria. However, many don’t realize that the same genetic mutation responsible for these stones has been reported in over a dozen breeds of dog, although at a much lower frequency.

Urates are formed from uric acid, a product of the breakdown of natural compounds of the body and from our food, known as purines. Affected dogs are predisposed to the formation of these bladder stones due to a mutation in the SLC2A9 gene¹; a gene that serves as the blueprint for a protein responsible for transporting uric acid in the body. In dogs free of this mutation, this transporter plays an important role in transporting uric acid from the blood into the liver for degradation and from urine produced in the kidney, back into the blood. Affected dogs cannot perform these tasks adequately, thus resulting in a high level of uric acid in both the blood (hyperuricemia) and urine (hyperuricosuria). The disorder is inherited in an autosomal recessive fashion meaning ...
