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.
The average lifespan for small dog breeds ranges from 10 to 15 years, with some breeds living as long as 18 years. In general, small dogs live longer than their larger counterparts, with the shortest living breeds still exceeding the average lifespan of most large breeds.
Small dogs are considered senior citizens of the canine community when they reach 11-12 years of age. Their medium-sized friends become seniors at 10 years of age. Their larger-sized colleagues are seniors at 8 years of age. And, finally, their giant-breed counterparts are seniors at 7 years old.

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.
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.
He has lost interest in all or most of his favorite activities, such as going for walks, playing with toys or other pets, eating treats or soliciting attention and petting from family members. He cannot stand on his own or falls down when trying to walk. He has chronic labored breathing or coughing.
Not surprisingly, older dogs are increasingly vulnerable to diseases that may require anesthesia as part of the treatment process. Due to the natural physiological deterioration that occurs with age, experts estimate that the risk of anesthetic death increases as much as seven times for dogs older than 12 years of age.
Bluey, an Australian cattle dog, entered the Guinness Book of World Records by living to the ripe old age of 29 years and 5 months, setting the record for oldest dog ever. The record was set in 1939 and still stands, but many Australian Cattle Dogs have tried to beat it by living good long lives of their own.
Unexpectedly, life tables varied widely between breeds. Jack Russell Terriers had the highest life expectancy at birth (12.72 years), followed by Yorkshire Terriers (12.54 years), Border Collies (12.10 years), and Springer Spaniels (11.92 years).
Only 8 percent of dogs lived beyond 15, and 64 percent of dogs died of disease or were euthanized as a result of disease. Nearly 16 percent of deaths were attributed to cancer, twice as many as to heart disease. [...] In neutered males the importance of cancer as a cause of death was similar to heart disease.
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.
To estimate your dog's age you need to know its breed and that the first dog year is equal to 15 human years. The subsequent years of your dog are equal to 4-5 human years. As we said before, it all depends on what is the life expectancy of a dog with a certain breed but this is a good rough approximation.
This can take as little as 30 seconds (though it can be prolonged in certain individuals). This means that your dog will be asleep before their body shuts down, so will not feel any distress or pain at the point of death. They are as asleep as they would be for a surgical procedure.
You may see them twitch or take a final breath. This can be startling, but it's a normal part of the process. Your pet isn't in pain. Use of a sedative makes this step less likely.
All your dog feels is a tiny prick of the needle – then the injection is painless. Occasionally, a dog may give a small cry as the injection is given – as with all anaesthetics, there is a brief feeling of dizziness as the drug takes effect.
The most challenging time of raising a puppy is the adolescent period. Dogs become “teenagers” and seem to forget everything they have ever been taught. This period is individual to each dog, but it may begin when he's about eight months old and continue until he's two years old.
Do dogs eat more as they get older? Yes. Sometimes this is due to underlying health conditions, such as diabetes mellitus or Cushing's disease, or a medication they're taking, like prednisone.
Physical and Mental Development
A 16-year-old dog, depending on his size, is roughly the equivalent of an 80- to 123-year-old person. Like elderly humans, your dog is moving more slowly and sleeping more than he did in his spryer years. He may be showing signs of cognitive deterioration as well.
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.
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.
