5 Things You May Not Know About Your Dog's (or Cat's) DNA

When you bring a pet into your family, you quickly get to know their personality.

You learn their routines, their favorite toys, what makes them run… or purr.

But behind all of those traits lies an even older story: their DNA.

Today, pet DNA testing can reveal fascinating insights about our four-legged companions. While it can't answer every question, it can provide valuable information about their ancestry, inherited traits and, in some cases, their genetic health.

Here are five things you may not know.

1. Your dog may not be the breed you think it is

"He looks like a Labrador."

"We were told she's probably part German Shepherd."

When a dog is adopted—especially from a shelter—its appearance doesn't always tell the whole story.

In reality, many dogs inherit DNA from several different breeds over multiple generations. Some breeds leave obvious physical traits, while others leave almost none.

A DNA test compares your dog's genetic profile with a large breed database to identify the breeds that make up its ancestry.

Beyond satisfying your curiosity, these insights can also help explain certain behaviors, energy levels and physical characteristics.

2. Some diseases may be written in their genes… without ever developing

DNA testing can sometimes reveal that a dog or cat carries a genetic variant associated with an inherited condition.

However, this does not mean your pet will necessarily develop that disease.

Just like in humans, health is influenced by many factors, including genetics, nutrition, exercise, environment, veterinary care and lifestyle.

Rather than predicting the future, genetic testing identifies certain inherited predispositions that may help owners and veterinarians make more informed decisions about preventive care.

3. Two dogs that look alike can have completely different DNA

Have you ever met two dogs that looked almost identical but behaved completely differently?

That's perfectly normal.

Physical appearance reflects only part of an animal's genetic makeup.

Two dogs with similar looks may come from very different genetic backgrounds, which can influence their energy level, instincts, learning style and even certain inherited health risks.

DNA testing can help explain why two seemingly identical dogs are actually quite different.

4. Cats can benefit from genetic testing too

Most people associate pet DNA testing with dogs.

But cats have fascinating genetics as well.

Certain genetic variants have been linked to inherited conditions found in several cat breeds.

Knowing this information can help owners have more informed conversations with their veterinarian, particularly when there is a family history of disease or when breeders want to make responsible breeding decisions.

5. DNA tells a story… but never the whole story

This is perhaps the most important point of all.

A DNA test cannot tell you whether your dog will be happy.

It cannot predict how long your pet will live.

It cannot replace your veterinarian.

And it certainly cannot measure the love you share with your companion.

What it can do is provide valuable insights that help you better understand your pet and make more informed decisions throughout their life.

Genetics is a tool for understanding—not a crystal ball.

Know More. Care Better.

A pet DNA test isn't something every owner needs.

But for many families, it's an opportunity to better understand the companion who shares their everyday life.

To discover their origins.

To learn about inherited traits.

To answer questions that have remained unanswered since adoption.

At Adnà, we believe that knowledge is one of the best ways to care for the ones we love.

After all, they're family too.
