In this third part of a four part blog series examining preventable inherited diseases in the Labrador retriever (See previous blogs here; part one and part two) we will be examining a relatively common neuromuscular condition known as exercise-induced collapse and a skin disorder unique to the Labrador known as hereditary nasal parakeratosis.

Exercise-Induced Collapse

There aren’t many inherited diseases more concerning to Labrador lovers than exercise-induced collapse (EIC). This potentially fatal condition caused by a mutation in the DNM1 gene results in an inability to produce adequate amounts of a protein called dynamin 1, which plays an important role in nerve signal transmission in the body. As its name suggests, dogs affected with EIC typically present during periods of intense exercise, often before 2 years of age. During an episode of collapse, affected dogs will commonly develop an awkward, wobbly gait that progresses to severe weakness, dragging of the hind limbs, and collapse lasting for 5 to 10 minutes. Though unable to rise, dogs experiencing an episode of collapse are usually mentally alert and pain-free. Most dogs completely recover within 30 minutes and appear normal between episodes. Most concerning however, is that in some cases affected dogs can progress ...

It’s not hard to love a Labrador retriever. Their outgoing, family friendly personality, great rapport with children, receptiveness to training, and their ability to hunt both waterfowl and upland game have made them a highly desirable and well-loved breed. This popularity is reflected by their place at the top of the American Kennel Club’s registration statistics for the past 24 consecutive years.

When adopting or purchasing a new canine family member or hunting companion, we would all like to know that our enormous investments in love, time, and money will see a sizable return. For a family dog, we’d like to know that they will be healthy and live as long as possible. For a hunting or working dog, in addition to a long life, we’d also like to know they will be able to have a long, healthy career performing the specific task for which we’ve prepared them. Though we could never eliminate or predict all disease risks for our dogs, genetic testing technologies have made elimination and prediction of some inherited diseases easier than ever before.

Throughout human history, people have learned to use a variety of animals to help perform essential tasks in an attempt to make their lives easier. While dogs are often recognized for their skill as hunters or as integral hunting companions in pursuit of a variety of game, one under recognized skill of dogs is as draft animals. While we often associate draft or sled dogs with competitive racing such as the Iditarod or Yukon Quest races, many do not realize that these races were developed from the historical use of dogs as draft animals. One dog breed with significant roots as both a hunting and draft animal is the Alaskan malamute.

Early accounts describe ancestors of the Alaskan malamute being used by the native Alaskan tribe previously known as Mahlemuts. These dogs played a crucial role in helping the tribe succeed in the harsh and unforgiving land of northwestern Alaska by assisting them with hunting and pulling sleds. When gold fever struck the Yukon and Alaska in the 19^th century, demand for malamutes and other capable draft dogs increased substantially to assist hopeful prospectors in their quest for a golden fortune. Often confused with the Siberian husky due to ...
