As entertaining, happy and hard-working dogs, golden retrievers have become one of the most popular breeds in the world. They consistently rank among the most-registered breeds in the U.S., U.K. and Australia, and serve many roles with an unrivaled eagerness to please.

Developed in Scotland in the 1800s as a water dog used to retrieve shot fowl, golden retrievers descend from a non-descript “yellow-colored” retriever, two extinct breeds (the St. Johns water dog and the Tweed water spaniel), Irish setters, the bloodhound and wavy-coated black retrievers. This combination of dogs set the stage for the modern golden’s characteristics: love of water, superb scenting ability, trainability, biddable disposition, desire to retrieve, soft mouth and intelligence. A well-balanced dog, golden retrievers possess soundness of body, character and intelligence (author Stanley Coren ranks them as the fourth most-intelligent dog).

While they were originally bred to retrieve waterfowl for hunters, and they still perform this duty today, golden retrievers have successfully crossed into all roles of canine athlete and assistance dog. Owners of golden retrievers compete in field trial and hunt tests, agility, flyball, obedience trials and the conformation ring. They are also used extensively in search and rescue, detection (from ...

You can now catch some great Paw Print Genetics information on The Working Man’s Retriever television show, which airs during “The Landing Zone” block of programming on the Sportsman Channel. You can also view each episode on the Paw Print Genetics YouTube page at any time!

Paw Print Genetics founder and CEO, Dr. Lisa Shaffer, a geneticist with more than two decades of experience, visits with host Dan Hosford and co-host Cynean Kenny in five separate episodes and discusses everything from the basics of how genetics work and the impact upon breeding decisions to when, how and why to test a new puppy and interpreting the results on your Canine Health Certificate.

Episode One: In the first episode of Working Man’s Retriever that Dr. Shaffer appears on, she discusses silent, or recessive genes; the differences between clear, carrier and affected dogs; how you can still safely breed dogs that are carriers of known genetic mutations and how, with consistent genetic testing you can eventually eliminate genetic mutations from your breeding program. She also touches on how a Canine Health Certificate adds value to a litter of puppies and acts as a safety measure for the puppy buyer.

The Spokane Police Department’s K-9 Unit is highly trained to fight crime and help keep our city safe. When highly trained canines used in police work are prematurely retired due to health issues, it costs the department extra resources and manpower to get new canines up to speed. German shepherds and Belgian malinois, two of the most popular breeds used for tracking, suspect apprehension, building and vehicle searches, as well as search and rescue, can cost tens of thousands of dollars. Even if the dog comes with a financial or replacement-dog guarantee, the weeks of specialized and intense training with officers represent an un-recoupable monetary loss in man-hours.

To that end, Paw Print Genetics recently collaborated with our hometown police force, the Spokane Police Department, and their K-9 Unit to genetically screen the six dogs patrolling our streets. While none of the hardworking dogs have displayed any sort of symptom related to genetic disease, the information gathered from the screening will give the department a baseline reading of each dog’s genetic health, which could be useful in future health screenings, any medical issues and treatments.

Additionally, and perhaps more importantly, the Spokane Police Department conducts a small breeding ...

Every breed of dog comes with drawbacks that we must accept as owners. It could be their size, how much they shed, physical requirements or limitations, or even the likelihood of developing genetic disorders. Knowing what you’re getting into, before you get into it however, can save you thousands of dollars and tons of heartache.

While you might love the looks and personality of a specific breed, you have to be honest with yourself as to whether or not you are capable of providing the dog with its required maintenance and if they honestly fit into your lifestyle.

Perhaps the best example of this honest assessment that I’ve read can be found in an article by Dr. Patty Khuly entitled "This Veterinarian’s Love-Hate Relationship with French Bulldogs."

In the article, Khuly outlines why she loves the French bulldog so much – their personality, looks and cuddle-ability among them. She’s also honest about how she’s come to own several over the course of more than a decade – primarily, owners that couldn’t afford the upkeep on dogs with severe issues, including cleft palate, dermatological problems and an emergency c-sections.

Before you blame the high-cost of veterinary care ...

Continuing the series on "when genes don't make sense," let’s talk about probabilities. Many people will hear that if a condition is recessive that one in four puppies will be affected or, if it is dominant, that 50% of the puppies will exhibit the trait or be affected with a condition. They will subsequently declare that because the outcome in their litter is different than these exact percentages, it therefore must not be… recessive, dominant or genetic at all.

On the other hand, many people in dogs will say things like "they need to breed a male in order to determine if he produces males or females."

These are different errors in reasoning relating to the same type of probability.

In the first case, people are expecting the actual results to be exactly what is predicted based on possible results or probabilities. In the second case, people are assigning meaning to the random variation that is usually observed (and actually expected) compared to what is predicted based on probability.

To start with the second scenario, millions of sperm are swimming as hard as they can to fertilize the eggs. Roughly 50% of these sperm carry an X chromosome ...

At least 33,000 years ago, humans began the process of domesticating certain members of the gray wolf species. Since that process began, humans have genetically manipulated canines to fill various roles – beginning with tasks that increased means of survival and later to simply serve as companions. Those evolutionary changes have been a benefit to humans, but have caused health issues within many dogs – because as we’ve bred for desired physical traits, detrimental genetic mutations have also been passed along within many breeds.

The consistent selective breeding of canines has led to hundreds of breeds with standard and predictable attributes, or traits.

For example, the short-legged, long-bodied dachshunds allowed them to easily enter underground tunnels and burrows of badgers and other small animals; long-eared, keen-smelling bloodhounds were bred to trail deer, wild boar and later humans; some of the oldest breeds, the sight hounds, which include greyhounds, whippets and saluki, were selectively bred for long legs, strong aerobic endurance, sharp eyesight and the desire to chase feathered and furred game.

These consistent traits were brought about by mixing several different canines that possessed desired attributes (i.e., flat-coated retrievers were likely a combination of St. John’s Water Dogs ...

Throughout the evolution of the modern canine, one of the most important symbiotic relationships with humans has been as the role of protector by the dog.

Those wolves that stuck close to humans in hopes of scavenging leftovers, and which slowly evolved into modern canines, provided early man with advanced warning systems and protection when other wild creatures in nature provided a much greater threat than they do today.

However, not much has changed in tens of thousands of years. Today’s dogs are used by the military, businesses and in homes throughout the country (and world), for protection and guard duty.

In fact, the right dog in a home can be a greater deterrent for criminals than the presence of a firearm. In a study that involved 589 convicted property offenders, the question was asked: “How effective is each of the following likely to be in preventing burglary, breaking and entering and grand theft?”

The results were:

0: not effective; 1: somewhat effective; 2: very effective

Monitored burglar alarms: 1.51
Electronic sensors in windows: 1.35
Closed circuit TV cameras in stores: 1.31
Private security patrols: 1.14
DOG IN HOUSE: 1.11
Weapons in home: 1 ...

A phenomenon in canine competition circles known as popular sire syndrome can produce strong, competitive and intelligent puppies that go on to become, and produce, champions. The occurrence can also produce puppies that fill the breeding pool with genetic maladies.

When a male dog wins a prestigious championship, he obviously has what it takes to win at the highest levels. The effect is that his value as a stud dog skyrockets as breeders with females hope to produce puppies that can replicate their father’s accomplishments.

Often that trendy stud dog is bred with many female dogs throughout the country. When this happens, you can see that male dog show up in pedigrees from previously unrelated lines. In a large breeding pool, say with Labradors, the effects aren’t as profound as in a smaller population, but they’re still present and can cause issues for future generations regardless of population size. If that popular stud dog has any genetic disorders in his DNA, his puppies will likely harbor those mutations – at best becoming carriers and at worst being affected with the related disorder – and can continue to contaminate the breeding pool.

Even in a large breeding population, the bottleneck ...

There’s a saying in dog breeding: "like produces like." A good breeder knows this and will attempt to pair dogs similar in conformation, drive, disposition and trainability together so the puppies will be of consistent and known quality.

When it comes to selecting a puppy that is to be used for a very specific task, such as hunting, the show ring, herding or guide and detection dogs, future successes and ease of training for those tasks are heavily dependent genetics. Finding the best line of dogs with proven genetics, as well as the disposition and conformation you want is most greatly influenced by the dog’s sire and dam.

Too often today it seems that an inordinate amount of emphasis is placed on the sire’s accomplishments and lineage. While selecting a sire with a pedigree decorated with titles, or one with comprehensive experience, from the venue you’re wanting to participate in is important, the dam’s genetics, disposition and pedigree are just as important, if not more so.

There’s a theory out there, one that I like to keep in mind when looking at pedigrees, which says the bottom line of a dam’s pedigree is ...
