The dog is a domesticated descendant of the wolf. Also called the domestic dog, it is derived from extinct Pleistocene wolves, and the modern wolf is the dog's nearest living relative. Dogs were the first species to be domesticated by hunter-gatherers over 15,000 years ago before the development of agriculture.
The aging profile of dogs varies according to their adult size (often determined by their breed): smaller dogs often live over 15–16 years (no longer than 20 years), medium and large size dogs typically 10 to 20 years, and some giant dog breeds such as mastiffs, often only 7 to 8 years.
Smaller dogs often live over 15 to 16 years. Whereas the medium and large-sized dogs typically live for 10 to 13 years, and some giant dog breeds such as mastiffs often live only for 7 to 8 years. So, the average lifespan for a dog is about 15 years. Q.
Medium-size dogs align more with the overall average dog lifespan of 10-13 years. But some medium-size dogs can be very long-lived; the oldest dog on record was a Rafeiro do Alentejo named Bobi, who's 30 years old and counting! Medium-size dog lifespans and diseases of concern vary from breed to breed.
According to the Guinness World Book of Records, the longest-living dog ever recorded was Bluey, an Australian cattle dog, who lived nearly 30 years!
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.
The “Seven-Year Rule”
Georges Buffon, an 18th-century French naturalist, had more or less the same theory: Humans live to 90 or 100 years, and dogs to 10 or 12.
RESULTS. Men aged 92 to 93 had an overall 6.0% chance of surviving to 100 years, whereas the chance for women was 11.4%. Being able to rise without use of hands increased the chance for men to 11.2% (95% confidence interval (CI) = 7.7–14.7) and for women to 22.0% (95% CI = 18.9–25.1).
In general, dogs go through five major life stages: puppy, young adult, mature adult, senior, and geriatric.
Sadly, most mammals technically age faster than humans. This is mostly because other mammals have different DNA to humans, giving them a higher heart rate and metabolic rate. As a result of these genetic differences between humans and dogs, dogs have bodies that go through more wear and tear sooner.
Affection, safety and love can work wonders in prolonging your dog's life. Treating your dog like a member of the family will only add to their health and wellbeing.
CONQUEIROS, Portugal (AP) — The world's oldest dog recently celebrated his 31st birthday, according to Guinness World Records.

There's no right or wrong answer. It's a personal matter for each pet owner. The goal is to keep your friend with you for as long as they are comfortable, but let them go if they are in pain.
Vestibular disease is the main reason why an older dog may experience a sudden loss of balance and an inability to stand or walk normally. How can you tell if a dog has a vestibular disease? A few of the signs include dizziness, stumbling or wobbly steps, and falling over.
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.
The most widely accepted earliest dog remains are those of the Bonn-Oberkassel dog which date to 15,000 YBP. Earlier remains dating back to 30,000 YBP have been described as Paleolithic dogs but their status as dogs or wolves remains debated.
"In shape, the Paleolithic dogs most resemble the Siberian husky, but in size, however, they were somewhat larger, probably comparable to large shepherd dogs," added Germonpré, a paleontologist at the Royal Belgian Institute of Natural Sciences.
She was 22. The 4-pound toy fox terrier died on Monday from natural causes – months away from her 23rd birthday, according to Guinness World Records. Pebbles spent her last moments in her South Carolina home, beside owners Bobby and Julie Gregory.
“The older they get, the more sleep they need, and that's OK,” says Dr. Rossman. 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.
The first year of a medium-sized dog's life equates to about 15 human years. Year two for a dog equals about nine additional human years, making the dog about 24 in 'dog years'. After age two, each human year adds around five dog years.
