DNA Testing for Dogs: Benefits and How It Works

DNA tests are commonly known for human applications like parentage and crime scene investigations, but DNA testing for dogs is increasingly popular in the UK and beyond. It is used not only by breeders to avoid hereditary issues but also by owners to learn more about their dog's breed mix and ancestry.

Testing involves taking a simple cheek swab from your dog and sending it to a laboratory, which returns detailed results that can reveal a dog's breed composition, health risks, and lineage. Below is a comprehensive guide to what dog DNA testing can offer you.

How DNA Testing for Dogs Works

Dog DNA testing is straightforward. You purchase a test kit from a reputable company, which typically costs between £100-£200. The kit contains materials to collect a cheek swab from your dog. After mailing the sample back, the lab analyses the DNA and returns results usually within a few weeks.

These tests detect genetic markers to identify breed ancestry, hereditary health traits, and sometimes physical and behavioural traits related to genetics. The process is non-invasive and safe for your pet.

Benefits of DNA Testing Your Dog

1. Breed Identification: DNA testing can accurately identify breeds present in mixed-breed dogs, helping owners understand their pet's temperament, care needs, and appearance.
2. Health Screening: Many tests screen for over 270 genetic health conditions. Knowing potential risks enables early veterinary intervention and better health management.
3. Hereditary Trait Detection: Tests can identify coat colour genes like the blue merle gene, which informs breeders about possible health concerns in offspring.
4. Informed Breeding Decisions: Reputable breeders use DNA testing to minimise inherited diseases and maintain genetic diversity, promoting responsible dog breeding.
5. Parentage Verification: Essential for registered pedigree dogs, DNA tests confirm parentage and support accurate pedigree records, especially in professional breeding programs.
6. Relatives Finder Services: Some DNA providers offer tools to discover genetic relatives, providing fascinating family history insights for your dog.
7. Better Health and Care: Understanding your dog's genetic makeup helps tailor diet, exercise, and veterinary care plans specific to their needs.

How to Get Your Dog DNA Tested

Choose a reputable DNA testing company. Popular providers include Embark, Wisdom Panel, and the AKC, each offering different focuses such as health, breed identification, or parentage verification. Purchase a kit, collect a cheek swab sample from your dog at home, then send it back as instructed.

Results will be given through online portals or reports. Use the insights responsibly, remembering that these tests supplement but do not replace veterinary care.

Reliability and Accuracy of DNA Test Results

While dog DNA tests provide valuable insights, some variability exists. Different companies use diverse genetic databases, and the complexity of dog breed histories can lead to discrepancies—especially in distant ancestry results.

For example, a healthy Chihuahua would very likely not show as mostly German Shepherd if tested. If precise results are required for breeding, vet-collected samples sent to certified veterinary labs offer higher reliability, albeit at increased cost.

Is DNA Testing Worth It?

For responsible dog owners and breeders, DNA testing is a valuable tool. It provides education about your pet, enables early health precautions, and helps in making informed breeding decisions. However, it should never replace regular veterinary checks or common-sense care.

Knowing your dog's breed ancestry and genetic health risks can bring peace of mind and deepen your bond with your pet.
