Life Expectancy Of Dogs: How Long Will My Dog Live?

Pug in old man's arms (caption: Life Expectancy Of Dogs)Larger animals tend to live longer than smaller ones (most of the time). Think about it. Humans live longer than cats, which live longer than a rat, which lives longer than a fly. But why isn’t this true when it comes to animals within their species?

A person who weighs 150 pounds will most likely live longer than a person who weighs 300 pounds. They live longer because of increased health risks for the person who weighs 300 pounds.

When it comes to dogs’ life expectancy, how can you compare a Great Dane to a Chihuahua? Their anatomic builds are completely different, and their lifespans reflect this. Beyond size, is there an average age of a dog based on breed or other factors? Yes. Let us explore this subject further.

What Determines A Dog’s Lifespan?

Want to know how you can help your pup live a longer, happier life? Below are some factors that help determine a canine’s lifespan.

Care

As the owner, you can affect the care you provide for your dog. A dog with a proper, nutritious diet and exercise can live longer than one without. In addition, taking your furry friend to annual wellness exams at the veterinarian and getting her booster shots can result in a healthy dog with a longer lifespan.

Size

Research shows that larger dogs live for a shorter period of time when compared to smaller ones. For example, an Irish Wolfhound (average 115 pounds) has an average lifespan of seven years, while a Jack Russell Terrier (average 15 pounds) can live up to 13-16 years.

Inbreeding can reduce the lifespan of canines. Cross-breed dogs have a longer lifespan in comparison. Inbred dogs have a risk of carrying genes for illnesses that are common to that specific breed. Further, “mutts” who have at least two breeds and commonly more tend to have the least health problems and live longer than their purebred counterparts.

Spayed Or Neutered

Spaying and neutering a puppy at a relatively young age can positively affect a dog’s lifespan. Most studies recommend surgical sterilization before five months of age for small breed dogs and 12-15 months for larger breed house dogs.

Recent studies show that these benefits may or may not be completely accurate, but there is no question that your life will be easier without a litter of puppies, and this will be less stress on your pup, which could mean a longer life.
