Comparison of Dog Ages
by Ron Kurtus (revised 13 September 2011)
Dogs age more rapidly than humans. One year for a dog is equivalent to between five and eight years of human life, depending on the size of the animal.
A dog has different nutritional and health care needs in the various phases of its life. Older dogs suffer from the same ailments as elderly people, such as arthritis and loss of hearing and vision. You can get a good idea of how to take care of your dog and also understand its behavior by examining the comparison of the actual age of your dog and the corresponding age of a human.
The same is true for cats and other animals.
Questions you may have include:
- What are the age phases in a dog?
- What are the age phases in a cat?
- What is the life span of other animals?
This lesson will answer those questions. Animal Health Disclaimer
Ages of dogs
Since dogs can vary from weighing only a few pounds to over 100 pounds, size is a major factor in the animal's longevity. Productive years are when the dogs are able to reproduce.

Summary
Most pets and other animals have a shorter life span that humans. With dogs and cats, a relationship between their age and the equivalent human age has been estimated. As they age, they require different care, as do humans when they age.
Dogs are wonderful companions
