Prevention Is Smart Breeding- PFK Deficiency in the English Springer Spaniel

Prevention Is Smart Breeding- PFK Deficiency in the English Springer Spaniel

Likely originating in Spain, the spaniel family of dogs have long been important companions to bird hunters around the world. As late as the 1880’s, springer and cocker spaniels were born in the same litters and were only differentiated by size after birth. Dogs under 28 pounds were considered “cockers” and were used for their ability to hunt the small wading bird known as the woodcock while the larger “springers” were used to flush game birds to be captured by trained birds of prey (which were later replaced by firearms). Separate breed status for cocker and springer spaniels was established in 1902 by the Kennel Club of England and the English springer spaniel (ESS) was formally recognized by the American Kennel Club in 1910. Since that time, the ESS has been further differentiated into the leaner and less densely haired “field” variety and the heavier boned and thicker coated show or “bench” lines.

Like other breeds, along the historical path to the modern ESS, the breed has developed some inherited disease concerns that keep breeders on their toes. Luckily, some of these inherited diseases can be eliminated from blood lines though the use of genetic testing technologies and selective breeding ...

My bird dog isn't hunting like he used to. What's wrong Doc?

My bird dog isn't hunting like he used to.  What's wrong Doc?

The season of the bird dog is upon us! Whether it's ducks, pheasants, geese or quail, your four-legged, bird-tracking machine needs to be well-trained and in optimal physical health if you want to improve your chances of collecting a limit. You handled the training through hours and hours of sacrifice, treats, frustration and love… and last year it showed. However, this year you are noticing that something is a little off with ol’ Chopper, and you can’t quite place what it is.

He seems unmotivated and won’t trail like he did last year. He acts like he’s excited for the hunt, but something is holding him back. Is it a health issue? Do you need to take him to the veterinarian? Given the immense financial, time and emotional commitments of purchasing and training a great hunting dog, wouldn’t it be nice to know that you’ve increased the chances of your hunting companion tracking birds with you late into their adult life? 

There are many different diseases or conditions that could take a bird dog off his game. Some of the most common ailments such as osteoarthritis, intervertebral disc disease, traumatic injuries and eye problems are called “acquired” diseases and ...

I perform genetic testing for CNM on my Labradors, but what is CNM?

I perform genetic testing for CNM on my Labradors, but what is CNM?

The popularity of the Labrador retriever doesn’t seem to wane.  It has been the number one dog breed registered by the American Kennel Club from 2002 to 2012 (the last time registration statistics were calculated) and is currently the most popular breed in the world.  Their cheerful dispositions, great prey drive, and high intelligence, has made them a common sight in American households.  Unfortunately, like many dog breeds, certain inherited diseases have become an issue as the popularity of the breed has increased.  One such disease, centronuclear myopathy (commonly referred to as “CNM” by Labrador breeders), has become a concern for the breed.  It is currently recommended (though considered optional) by the Labrador Retriever Club to perform genetic testing for CNM on all Labradors.  Despite that many Labrador breeders are currently testing for the disorder, from conversations, I have discovered that many breeders still have a significant number of questions in regards to what the disease actually is and what causes the symptoms seen in CNM.

CNM is a hereditary muscle disease of dogs caused by a genetic mutation in the PTPLA gene.  This disease was first described in dogs (Labrador retriever) in ...
