How we calculate Japanese Chin age
Our calculator uses the UCSD epigenetic formula published by Wang et al. in 2020, which maps dog age to human age based on DNA methylation patterns. Breed-specific lifespan data comes from the American Kennel Club and peer-reviewed veterinary studies. For a Japanese Chin specifically, this gives you a more personalized result than generic calculators.
