WoofAge - DNA Birthday Test

$159.99 $200.00

Reveal your dog's birthday! Unsure when your dog was born? Thanks to advances in DNA methylation science, WoofAge can now estimate your dog's calendar age and birthday with far more accuracy than simply looking at their teeth. Each test also includes a life stage report with tailored care tips for every age.

We believe there are roughly 15 million dogs with uncertain birthdays. Let's complete their story by giving them the gift of truly knowing their birthday, giving you one more reason to spoil them on their special day—and every day!

No one can tell exactly how old a dog is just by looking at them. That’s why we use the scientific field of epigenetics to estimate your dog’s age.

We trained the Age Test model using data from thousands of dogs with known ages, so that we can reliably estimate your dog’s age based on their DNA methylation profile. We’ll also give you information about the range of dates likely to contain their true birthday—called the “prediction interval.”

The "7 to 1" ratio of dog years to human years is a myth. Dog breeds age at different rates, with some smaller breeds living much longer than larger ones. WoofAge adjusts your dog’s human age based on breed and places them in one of five life stages: Juvenile, Adult, Mature Adult, Senior, or Geriatric.

As dogs age, their social, behavioral, and health needs change. Dogs who have the same calendar age may be at different stages in life, depending on breed, size, and other factors.

We’ll suggest appropriate diet, exercise, and preventative care options to keep your dog healthy at every life stage. Talk to your veterinarian to determine what type of care is best for your dog.

Developed by Ivy league scientists, WoofAge is the highest performing canine methylation epigenetic clock age predictor on the market where 80% of dogs have a true birthday within 12 months of their estimated birthday.

Determine Your Dog's Life Stage in Human Years

The common "7 to 1" ratio of human years to dog years is a myth. In reality, no two dog breeds age at the same rate. For example, a Chihuahua typically lives much longer than a Great Dane. So, how old is your dog in human years? It’s likely not what you think.

Because breeds age differently, WoofAge adjusts your dog’s human age based on breed-specific factors. Whether your dog is a centenarian or about to celebrate its first birthday, WoofAge will place your dog in one of five life stages: Juvenile, Adult, Mature Adult, Senior, or Geriatric.
