Things to take into consideration when calculating a dog's age:
Dogs overall health
According to the American Veterinary Medical Association, puppies age 15 human years in their first year regardless of breed. Then their 2nd year is equal to around 9 human years, from here it varies on the size of the dog. Dog's mature quickly from childhood to adulthood. Two years after a dogs birth, the dog will typically have aged 24 human years.
Aging then slows down to about 4-5 years for each calendar year. Usually smaller dogs live longer than larger dogs, according to some research this may be related to large breed puppies having too many excess free radicals for antioxidants to fight, likely because large breed puppies have fast metabolisms, thus requiring more energy. If these findings are proved correct, it may be possible to extend large dogs lives with antioxidant supplements. There are many theories around aging of larger breeds.
There is currently a Dog project that is working on extending the period of life in which dogs are healthy.
There are things that can be done to help a dog's health
Diet: Feeding the dog healthy food without chemicals in it
Dental Hygiene: Brushing your dog's teeth reguraly can reduce the change of infection
Obesity: Try to get your dog 30 minutes of exercise a day, some breeds need more such as a german sheperd.
Generally, dog breeds are separated into three types once they are full grown:
Small: 20 lbs or less
Medium: 21-50 lbs
Large: 50 lbs or above
