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.
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 will do our best to help you estimate calendar age. Please work through the questions found in the following blog post as a starting point, and then reach out to us: How Old is Your Dog?.
