A dog DNA test is part fun ('so THAT'S why he digs') and part genuinely useful — many screen for hereditary health conditions that let you and your vet get ahead of problems. Here's how the top tests compare and what's actually worth paying for.
Breed-only vs. breed + health
Cheaper tests identify breed makeup only. Pricier kits add health screening for dozens or hundreds of genetic conditions, plus traits and sometimes a relatives-finder. For a mixed-breed rescue, the health screening is the part with real value — it can flag medication sensitivities and breed-linked risks before they become emergencies.

Breed identification from the leading tests is quite reliable, especially for common breeds, thanks to large reference databases. Health screenings are valuable as early-warning flags but should always be confirmed and interpreted with your veterinarian rather than acted on alone.

For a rescue or mixed-breed dog, spend up for the version with health screening — the insight into hereditary risks is worth far more than the breed breakdown alone.
