Doggie DNA Dilemmas. The Drawbacks of Canine Genetic Testing

Privacy Concerns

One issue to consider with dog DNA testing is privacy. When you submit your dog’s DNA sample to a testing company, they end up with your pet’s entire genetic code in their database. While some testing companies claim to keep this data confidential, there have been cases where DNA testing companies have shared or sold customer data without consent for research or other business purposes.

For example, in 2018 it was revealed that GlaxoSmithKline purchased access to consumer data from the DNA testing company 23andMe. This included genetic information from millions of 23andMe customers, allowing the pharmaceutical company to use that data for drug development research. Such sharing and selling of genetic data raises privacy concerns since pet owners may not have realized their dog’s DNA could be passed along to third parties without their explicit permission.

Overall, while DNA testing your dog can offer some intriguing insights, pet owners should be aware that this may come at the cost of relinquishing control over their pet’s genetic privacy. Dog DNA databases could potentially be hacked, seized by law enforcement, or shared with pharmaceutical firms or other companies without the owner’s knowledge or agreement.

Data Security

DNA tests for dogs require owners to submit their pet’s genetic material to a company for analysis. This raises concerns over the security and privacy of the DNA data. There is the potential risk that databases containing dog DNA profiles could be hacked or breached.

Genetic data is highly sensitive and personal in nature. If a dog DNA database was compromised, it could allow malicious actors to access information about people’s pets. A data breach could reveal insights about a dog’s origins, health conditions, and more.

Companies that analyze dog DNA test kits should have robust cybersecurity measures and encryption in place. However, no system is completely impenetrable. There are always vulnerabilities that sophisticated hackers could exploit to gain unauthorized access to genetic data.

Owners who wish to test their dog’s DNA need to be aware of the data security risks. While the convenience and insights DNA tests provide may be appealing, people should weigh the potential privacy trade-offs.

Limited Information

DNA tests for dogs only look at a small portion of a dog’s genetic code, usually less than 1% of their total DNA. This means they can miss key information related to the dog’s health and ancestry. While some tests may check for common genetic diseases, they cannot test for all disease-causing mutations. There are many rare conditions and complex traits that these tests simply aren’t designed to detect. Owners may get a false sense of certainty about their dog’s health by only looking at the limited set of results from a DNA test. They may miss signs or symptoms of conditions not covered by the testing and fail to take preventative measures. While DNA tests can provide some useful information, they provide an incomplete picture of a dog’s overall genetic health and ancestry.

Overreliance on Breed

One potential drawback of dog DNA tests is placing too much emphasis on breed as a predictor of health and behavior. While breed ancestry provides some useful information, it does not offer a complete picture. Breed tendencies are just broad generalizations and may not apply to each individual dog.

A dog’s health and personality is also shaped by many other factors, including early life experiences, training, diet, exercise and overall care. Two dogs of the same breed can have very different characteristics based on their unique life histories. Furthermore, most dogs today are mixed breeds, with wide genetic variety even within the same litter.

People who over-rely on DNA test breed results risk pigeon-holing dogs into expected traits that may not fit the individual. Breed is an interesting ancestry detail, but it does not determine who a dog is or will become. Focusing too much on breed from a DNA test can create unrealistic expectations of dogs and misses the bigger picture of each dog’s individuality.

Misleading Health Predictions

DNA tests for dogs often provide health markers and predictions based on a dog’s genetic makeup. However, these predictions do not account for lifestyle and environmental factors that also play a significant role in a dog’s health and disease risk. A DNA test may predict your dog is at high risk for a certain condition, but that does not mean they will definitely develop it. Likewise, a low-risk prediction does not guarantee your dog will never get sick.

A dog’s daily diet, exercise routine, chemical exposures, stress levels, and other environmental influences affect gene expression and health outcomes. Two dogs with the same genetic markers can have very different health trajectories based on their living conditions. DNA tests provide limited value for predicting future health without considering the whole picture.

Questionable Breed Identification

DNA tests for dogs rely on algorithms and databases to compare a dog’s genetic markers to various breeds. However, some experts argue these tests cannot accurately identify all breeds in a dog’s ancestry. First, not all dog breeds have had their DNA profiled and included in the databases. This limits the ability to detect less common breeds. Second, dogs have been interbreeding for centuries, making their genetics incredibly complex. The tests can really only identify the most dominant breeds in a dog’s recent ancestry. Any breed further back simply won’t show up. This leads to test results that may omit significant parts of a dog’s breed makeup. The algorithms also struggle to differentiate between some closely related breeds. Overall, the breed identification from dog DNA tests should be taken as a best guess rather than an absolute result.

Creates Unrealistic Expectations

With the rise of dog DNA testing, some owners may develop unrealistic expectations about their pets’ health and behavior. Many people see dog DNA tests as providing definitive predictions about disease risk, life expectancy, personality traits, and more. However, these tests only examine a limited number of genetic markers and cannot account for the multitude of environmental and lifestyle factors that also influence a dog’s health and behavior.

Some owners may make significant decisions based on the limited information provided by DNA tests, such as breeding dogs they believe have superior genes, altering their veterinary care, or even euthanizing a dog predicted to develop a devastating illness. However, these tests do not provide the full picture. Basing major life decisions on DNA results alone, without considering all factors, can have detrimental consequences.

Rather than creating rigid expectations, owners should see DNA tests as one useful piece of their dog’s overall health and wellness puzzle. While genetic risks are important to understand, dedication to proper diet, exercise, training, veterinary care, and a loving home remain key to giving dogs their best lives. Dog DNA tests should open conversations with veterinarians, not close doors.

Can Cause Stress

Learning about potential health issues could worry some owners. While some see DNA tests as empowering by giving them information to prepare, others may find the results anxiety-provoking. Owners could become stressed wondering if their dog will develop a disease, especially those that are genetically predisposed to certain conditions like cancer or heart disease. This could lead some owners to over-monitor their dog’s health or have difficulty enjoying time with their pet. There’s also the risk of false positives or limitations in predicting disease later in life. Overall, the uncertainty from DNA results could negatively impact some owners’ peace of mind.

Expense

Dog DNA tests can be expensive, especially for owners who want to test multiple dogs. The tests typically range from $60 to over $150 depending on the company and amount of information provided. While the one-time cost may seem high, it does provide a lifetime of information about your dog. However, some owners may balk at the upfront cost, particularly if they have several dogs they want to test. There are occasionally discounts and bundle pricing available, but the tests still require a significant amount of money upfront. For owners researching their options, this financial investment should be factored into the decision making process before purchasing a dog DNA test.

Fear of Results

Some dog owners avoid testing out of fear of discovering potential health problems. Genetic testing can identify breeds that have hereditary conditions or reveal health risks an owner may not have considered. Getting news about a dog’s increased chances of developing certain diseases in the future can be emotionally difficult for some owners. They may prefer not knowing rather than facing the stress or challenges of caring for a dog with health issues. Without genetic testing, owners can maintain hope their dog will live a long and healthy life. For certain owners who become very attached to their pets, testing may open up scenarios they would rather not confront unless absolutely necessary. Avoiding testing eliminates the possibility of finding out bad news.
