We estimate genetic age and can try to help you with calendar age
Genetic age: First, we use your dog's reported calendar age and sex as a starting point. Our proprietary algorithm factors in breed breakdown (large dogs mature differently than smaller ones), genotype at size genes (more than 15 of them), and inbreeding coefficient. All of these have an effect on lifespan. The number we provide is where a dog is in his or her life relative to an average human living in the U.S.
In order to calculate your dog's genetic age, you'll need to enter in your dog's birthday (an estimate is fine!). How do I add or edit my dog's birthday?
Calendar or biological age: While some human DNA tests can estimate biological age, no commercial dog DNA test currently offers this sort of testing. However, we have some tips on how you (or your vet) can help you estimate calendar age in our blog post How Old is Your Dog?.
