One caveat: this group of dogs represented a population of sick animals that had come to the vet, so the average lifespan in this study is likely lower than that of dogs in general. Dogs, of course, share their lives with humans, meaning many of the factors that impact our health can also affect them.
Our two species have the same reproductive hormones in common, too, including progesterone and testosterone, which can both suppress the immune system and perhaps make a dog or person more susceptible to disease. And when it comes to lifespan, size matters.
Dogs have not two but four genders. That is:. And the interesting thing is neutering DOES have an impact on life expectancy: But for better or worse? The following information is fact. The prize for being in first place neutered females , is a clear six-months increased life expectancy than the second placed dog entire males.
Of course, this is an average, so there will be entire males that live longer than neutered females, and entire females that outlive entire males…but rule of thumb is neutered and female is a winning combo in the lifespan stakes. Another quirk thrown up by the data is that young male dogs are more likely to meet an untimely end, than females. Although we can guess at the reason perhaps they run off more or get into fights in truth, this needs more research to be sure. Actually, the different genders carry different risks.
The most common conditions that impact on lifespan are:. But this is where it gets confusing, because both desexed males and females carry a higher risk of getting cancer during their lifetime…. This takes a bit of getting your head round. Again, the implications of this need further research. By the law of averages, a neutered female dog has the greatest probability of a long life.
But the story is more complicated than this and you can influence events. For example:. Giant breeds have a single figure life-expectancy whilst small dogs off live well into their teens.

Other influencing factors can include lifestyle, how much exercise the dog gets, whether or not the dog has been spayed or neutered, and health care or lack of it. A basic and very general way people have attempted to calculate their dog's age in "people" years is by simply multiplying the dog's chronological age by seven.
This has found to be inaccurate because dogs age more quickly during the first few years but the aging process slows down after about two years. A more accurate calculation put forth on the VetInfo website is to consider a dog's first year to equal about 15 human years, with the dog being roughly 24 years old at the end of her second year.
After the second year, adding 4 human years for every dog year will give a closer to true age for your dog. Even though you can't compare it year for year, dogs and people age similarly. You and your dog will both go through the stages of youth and middle age before becoming senior citizens. And just like with people, there are preventative measures you can take to extend your dog's life.
Feeding her quality food that provides good nutrition is a start.
