DNA tests for dogs and pets

What is a DNA Test for Dogs and Pets?

Just like humans, our pets also have a unique DNA profile which is inherited from their parents. By analyzing a cheek saliva swab or the cells in a hair sample or blood sample, scientists can break down details about an animal’s species, genetic health, and other important details.

What Are the Top 5 Dog DNA Tests?

These are the 5 companies you should consider:

1. GPS Origins   


  • Price: $125 for each of 2 dog tests

The Health Screen and Life Plan scans your pet’s DNA for over 150 genetic diseases and health traits, including tendencies to react to some medications.

How Do You Perform a DNA Test on Your Pet?

Once you’ve decided to do a DNA test on your pet, the process is pretty straightforward.

  1. Buy a DNA testing kit and read the instructions carefully.
  2. Swab the inside of your dog or cat’s cheek with the enclosed brush or scraper to get a saliva or cell sample.
  3. Carefully package your pet’s DNA sample according to the instructions. You might need to pack it in a tube, let it air dry, or wrap it in a particular way to preserve the genetic material.
  4. Send your pet's DNA sample to the company's address, and prepare to wait. It commonly takes about 6-8 weeks to get a reply, usually via email, about your pet’s genetic makeup.

What Can You Learn from a Pet DNA Test?

A pet DNA test can tell you more than you'd expect about your furry or even feathered friend. Here is some potential information you can discover from your pet DNA test:

  • Your dog or cat’s breed. If you own a rescue cat or dog or just have a simple ‘mongrel’ mutt, a pet DNA test can tell you the main types of dog or cat—do you have a Persian Blue in disguise or a playful Labrador-cross?
  • Your pet's sex. This is particularly relevant for birds since it's often difficult to tell if you have a male or female. DNA testing uncovers male or female chromosomes to give you a definitive answer.
  • Your pet’s genetic health profile. Persian cats have a tendency to develop Polycystic Kidney Disease (PKD), and some dog breeds like collies are likely to react badly to certain common medicines. Knowing your pet’s inherited health issues means that you’re better able to be proactive in treating them.
  • An animal’s potential size and characteristics. If you’re thinking of adopting a rescue dog, you might want to know how big it will grow and its potential temperament.
  • Your pet’s health needs. Knowing your dog or cat’s breed means that you can make sure that they get enough exercise and the best kind of pet food for their type.

What’s the Difference Between Dog DNA Tests and Other Pet DNA Tests?

All DNA tests are similar in that they all analyze DNA samples for unique genetic markers. But, dog DNA tests only test for canine markers, so there’s no use testing the system by sending your cat’s DNA instead. Cat DNA tests look at feline markers, but they usually also use a cheek saliva swab. There are also equine (horse) DNA tests, which use the root of the horse’s hair, and bird DNA tests, which analyze the bird’s toenail clippings or feather root.

Are Pet DNA Tests Accurate?

Everyone wants to know whether they can rely on the results of their dog DNA test. Like human DNA tests, some are more accurate than others. Most pet DNA tests are pretty accurate, but their reliability depends on a few issues:

  • The quality of the DNA sample, so it’s important to follow instructions correctly
  • The number of genetic markers examined by the test company
  • How many breeds are in the test company’s database—the more breeds, the more accurate the results will be
  • Whether your dog is a first or second generation from a purebred. The purer the breed, the more reliable the result


Whether you’re curious about your mongrel’s breeds, want to know more about how to keep your pet healthy, or need to check your puppy’s sire, there’s a dog DNA test that provides reliable and accurate results. Indulge your curiosity today.
