Factors that Affect Dogs' Life Expectancy
  • The size of the dog is a major factor that determines its life expectancy. It has been observed that large-sized dogs have a shorter lifespan, as compared to small-sized dogs.
  • According to statistics, female dogs outlive their male counterparts by an average timespan of around one and a half years, especially the spayed ones.
  • Spaying or neutering, if done at a very young age, may positively affect the life expectancy of dogs. It has been suggested that these procedures may reduce the risk of cancer in ovaries, breasts, and testicles.
  • Inbred dogs have a shorter lifespan when compared to cross-breeds. Extensive inbreeding is one of the reasons for genetic illnesses that are common to that particular breed.
  • Above all, proper dog care is very much important as far as canine lifespan is concerned. A proper and nutritious diet and exercise, along with necessary health care can make your dog healthy and live longer.
In short, there are various factors that can positively or negatively affect the lifespan of a canine. Some of these factors (like genetics) cannot be rectified, but dog owners can take proper care of their pets, so that their canines live longer. Contact your vet, if you have any doubts regarding the physical condition and overall health of your dog.
