What dog DNA tests actually tell you (and what they don't)
A clear-eyed look at the three main categories of canine DNA test on the market — and which one matches what you're actually trying to learn.
Not all dog DNA tests are doing the same thing. There are three broad categories, and they answer very different questions.
Breed-ancestry tests tell you what breeds make up your dog's genetic background. They're great for satisfying curiosity and understanding inherited traits like coat type, size, and temperament tendencies.
Health-marker tests look for specific genetic variants associated with certain wellness considerations. They tell you about genetic predisposition, not present-day diagnoses. Most dogs come back negative across the panel.
Epigenetic tests — the newest category — measure biological age by looking at chemical patterns on DNA that change with age and lifestyle. They tell you how fast your dog is aging biologically, regardless of breed or genetic predisposition.
Which one matters depends on what you're trying to learn. If you want to know what your dog is — choose breed ancestry. If you want to know what to watch for — choose health markers. If you want to know how your dog is aging right now and what you can do about it — choose epigenetic.
Some kits (like ours) combine all three into one swab. That's the most complete picture, but each one alone tells you something different and useful.
