We've all been told that you can figure out your dog's "human age" by taking their actual age and multiplying by 7. Boom. Your 4-year-old dog is 28. Your 10-year-old dog is a senior at 70.
But new research says that's all wrong.
University of California San Diego School of Medicine says the old way doesn't work because dogs don't age at the same rate as people.
Dogs age quicker when they're young. But by age 7, things really slow down. Researching with labrador retrievers, they found the dogs that are 1 year old are more like a 30-year-old human. Aging slows down. When they're 4, they are similar to a 52 year old person.
Unlike the old system, dogs in their teens are more like 70, not 100 years old.
