Dog DNA Testing – 6 Myths Busted

Over half a million dogs have had their DNA tested in the last decade. DNA tests are no longer rare—they’re common tools. But common usage doesn’t mean common understanding. 

According to research, the pet DNA testing market was worth $322 million in 2022. 

With misconceptions abound, such as “this test won’t tell me anything I don’t already know”, or “nothing useful”. It’s easy to see why some people are skeptical. 

That’s where we come in.

Welcome to “Dog DNA Testing Myths Busted”. Here we’re going to debunk 6 common myths behind Doggy DNA testing.  We’ll clear up misunderstandings with hard facts. Get ready for a myth-busting deep dive into the world of canine genetics. 

Let’s get started.

Myth #1: Dog DNA Tests Are Only for Purebred Dogs

This myth has its roots in the early days of dog DNA testing when such tests were primarily used by breeders and kennel clubs to confirm the pedigree of purebred dogs. Many believe that since purebred dogs have a known lineage, DNA tests are only useful in their case.

In reality, DNA tests are invaluable for all dogs, not just purebreds. For mixed breed dogs, these tests can reveal the combination of breeds that make up their unique genetic mix, giving insights into their behaviour, personality traits, and potential health issues. Even for purebreds, DNA tests can identify inherited diseases, helping owners take preventative measures. So, no matter the breed, DNA tests offer useful insights for every dog and their human companions.

Myth #2: Dog DNA Tests Cannot Accurately Determine Breed

Many dog owners are skeptical of Dog DNA tests. This may be due to a lack of understanding about the advancements in dog DNA testing. Some people hold on to the idea that physical appearance is the most reliable way to determine a dog’s breed.

Modern veterinary science tells a different tale. Today’s dog DNA tests are based on extensive genetic research and use comprehensive databases of breed-specific genetic markers. Manufacturer Wisdom Panel claims 98% accuracy in its DNA tests. Furthermore, because a dog’s physical traits are determined by a small percentage of their genes, DNA tests can reveal hidden breeds that are not apparent in a dog’s outward appearance. Therefore, contrary to the myth, DNA tests can very accurately determine a dog’s breed.

Myth #3: Dog DNA Tests Can’t Provide Accurate Health Information

This myth likely stems from a limited understanding of the scope of genetic testing. Initially, dog DNA tests focused primarily on breed identification, leading to the misconception that they can’t provide health-related information.

Today’s dog DNA tests go far beyond breed identification. They can identify genetic markers for dozens of hereditary diseases and health conditions such as degenerative myelopathy, multidrug resistance, and Von Willebrand’s disease, to name a few. 

Knowledge of these genetic predispositions allows dog owners and their veterinarians to tailor preventive care, diet, and lifestyle adjustments to manage potential risks. So, contrary to the myth, dog DNA tests can indeed serve as an essential tool in proactive pet healthcare.

Myth #4: All Dog DNA Testing Kits Give the Same Results

This myth likely arises from the assumption that all tests work the same way and use the same resources, leading to the belief that results should be identical regardless of the testing kit used.

In fact, different dog DNA tests can yield different results due to variations in methodology, the number of genetic markers analysed, and the breadth of their breed databases. While some tests focus on a basic panel of genetic markers, others use more extensive panels for higher resolution results. Also, some tests have larger breed databases than others, enabling them to identify a wider variety of breeds. Therefore, it’s important to select a reputable testing service that utilizes comprehensive genetic analysis and an extensive breed database to ensure the most accurate results.

Myth #5: Dog DNA Tests Aren’t Useful for Dog Trainers or Behaviourists

This myth seems to stem from the belief that dog behavior is learned and largely determined by environment and individual experiences, rather than genetics.

While it’s true that environment and experiences play a significant role, genetics also heavily influence a dog’s behaviour, temperament, and response to training. Certain breeds are known for specific traits — Border Collies for their high intelligence and focus, Labradors for their sociability, and Basset Hounds for their independent streak. 

Knowing a dog’s breed makeup can provide trainers and behaviourists with valuable insights into potential behaviour patterns and training approaches. A Border Collie mix, for example, may respond well to tasks that engage their problem-solving skills. Thus, contrary to the myth, dog DNA tests can be a valuable tool in crafting effective training strategies.

Myth #6: Dog DNA Tests Are Too Expensive for the Average Pet Owner

This myth probably stems from the misconception that all genetic testing is expensive, a notion likely borrowed from the human healthcare field where genetic tests can indeed be costly.

The truth is, the price of dog DNA tests varies widely based on the comprehensiveness of the test. Basic tests can start as low as $70, with more comprehensive ones that test for numerous health conditions and traits being priced higher. 

The value they offer, however, can be immense. Understanding your pet’s breed makeup can inform their dietary needs, exercise requirements, and potential health risks. It enables tailored care that can contribute to their longevity and well-being. When viewed as a long-term investment in your pet’s health, the cost of dog DNA tests is reasonable and accessible to many pet owners.

Wrapping up our DNA testing Myth Busting

In the rapidly evolving world of canine genetics, dog DNA tests have proven to be a game-changer. They’re not just for the purebred dogs, they’re not inaccurate, and they definitely don’t limit themselves to breed identification. From providing valuable health information, to offering insights for trainers and behaviorists, DNA tests are a veritable treasure trove of canine insights.

Different tests do yield different results, and that’s not a drawback – it’s a feature. The diversity in testing options allows you to choose the best fit for your needs and budget. Dog DNA tests are not extravagantly priced gadgets, but rather, they’re valuable tools that help us provide the best care possible for our furry friends.

The world of canine DNA is intricate, beautiful, and immensely informative. We hope that we’ve helped bust some of the myths that cloud the understanding of this field. The next time you hear one of these myths, we hope you’ll be armed with the facts to set the story straight. Remember, knowledge is not only power—it’s also the way we give our pet companions the best lives possible.
