As a general guideline, though, the American Veterinary Medical Association breaks it down like this: 15 human years equals the first year of a medium-sized dog's life. Year two for a dog equals about nine years for a human. And after that, each human year would be approximately five years for a dog.
The first year of a dog's life is equal to 15 human years. The second year of a dog's life is equal to about nine human years. Each additional year is equal to about four or five human years.
So a 7-year-old dog would be roughly 62.1 human years old.
If a dog lives to 12 years old, that would equal 84 in human years (if you allow seven human years per one dog year), which sounds fairly reasonable.
Well, dogs are in possession of faster metabolisms and hearts that work harder than our own. Because of all this extra work, dogs age faster and, consequently, live shorter lives. It also means they grow up more quickly. A dog that's a year old is the equivalent of a human child ready to start school.
A 13- to 15-year-old dog, depending on her size and health, is roughly equivalent to a 70- to 115-year-old person. In her elder years, it is harder for your dog to learn new things. In fact, she likely will be resistant to changes in her surroundings and routine.
A 10- to 12-year-old dog, depending on his size and individual variation, is roughly the equivalent of a 60- to 90-year-old person. By now, you've likely realized that your dog is slowing down. He may still enjoy a long walk, but he is not quite as zippy as he used to be.
If you're anything like us, you'll probably continue referring to your dog as a puppy until they're old and grey! But generally speaking, a puppy is officially considered an adult dog between the ages of 1 - 2 years, once their bones have fully developed and they've reached their final height and size.
Like many animal species, the answer lies in how fast they grow and develop. Dogs grow faster than humans, and therefore, their entire lives are accelerated. Humans, for example, don't start developing teeth until around month 4. Dogs, on the other hand, start teething when they're around 3 or 4 weeks old.
Although all puppies are officially considered adult dogs once they reach one year old, puppies continue to grow in height and size while their bones are still developing, which takes anywhere from 6 to 24 months. Their skeletal growth is what determines how tall they will become as adults.
A dog is no longer a puppy between 12 to 18 months with some variation based on breed, size and personality. Smaller breeds tend to develop and reach maturity sooner, both physically and emotionally versus large to giant breeds that can take up to almost 24 months before reaching adulthood.
According to the well-known ''rule of paw,'' one dog year is the equivalent of 7 years.
Licking is a natural and instinctive behaviour to dogs. For them it's a way of grooming, bonding, and expressing themselves. Your dog may lick you to say they love you, to get your attention, to help soothe themselves if they're stressed, to show empathy or because you taste good to them!
Most dogs enter their senior years at around 7 years old, a little sooner for larger dog breeds. They begin to slow down, they may gain weight more easily, their senses start to dull. An older dog's behavior will give you plenty of hints as to what he needs, but sometimes it helps to put it in words.
Just like senior citizens need more sleep, an older dog sleeps a lot when compared to their younger counterparts. On the higher end of the scale, a senior dog can sleep up to 18-20 hours a day, says Dr. Rossman. She estimates that the lower end is probably around 14-15 hours per day.

The greatest reliable age recorded for a dog is 29 years 5 months for an Australian cattle-dog named Bluey, owned by Les Hall of Rochester, Victoria.
A dog's first year of life is the equivalent of about 15 human years. A dog's second year is the equivalent of nine human years (making a 2-year-old, medium-sized dog about 24 years old in human years). From the third year onward, each canine year is the same as about five human years.
The smaller breeds of dogs tend to live the longest. Yorkshire terriers, Chihuahuas, Dachshunds, Toy Poodles and Lhasa Apsos are the breeds who typically live the longest with these averaging a lifespan of up to 20 years.
A young dog can hold their pee for up to 10-12 hours if needed, but that doesn't mean that they should. The average adult dog should be allowed to relieve itself at least 3-5 times per day. That's at least once every 8 hours.
Unsurprisingly, dogs who enjoy a healthier diet and more exercise tend to outlive those who don't. Here are a few preventative measures you can take to make sure you get as many happy years with your dog as possible.
