How Old Is Your Pet?Understanding the way your pet develops over the years can be basically broken down by reviewing his or her general age in human years, which can be done with a few simple calculations.

 AGE CALCULATOR FOR DOGS: 

  1. At 1 year add 15 human years
  2. At 2 years add 9 human years
  3. For every year 3 and over add 4 human years
  4. (FOR MEDIUM/LARGE DOGS) For every year 6 and over add 5 human years

 AGE CALCULATOR FOR CATS: 

  1. At 1 year add 15 human years
  2. At 2 years add 9 human years
  3. For every year 3 and over add 4 human years

Examples: A nine year old cat will be (15 + 9 + 4 + 4 + 4 + 4 + 4 + 4 + 4) = 52 human years and an eight year old Great Dane will be (15 + 9 + 4 + 4 + 4 + 5 + 5 + 5) = 51 human years.

Please keep in mind that some factors, such as breed, heredity, care, activity, general wellness and veterinary care, may affect the calculations and the estimates are of a general nature. For example, some purebred dogs and cats (like Maincoons and Border Collies) mature at a slower rate and don’t see full maturity until they reach around 3 years.

It is safe to say that, apart from breed and heredity, you have a lot of control over your pet’s aging development by giving them the best care you can.
