For pet owners who want a dog that will have many years with them, you likely want to invest in a breed that traditionally has a long lifespan.

Here are some of the breeds with the longest lifespans.

6. Cockapoo


Hybrid dogs have become all the rage for many Americans–and even those across the world. One of the most popular hybrids is the Poodle with another dog breed. In the case of the Cockapoo, the hybrid is made up of a Poodle and a Cocker Spaniel.

Many pet owners love the benefits that the two breeds offer. You have a minimal shedding dog thanks to the Poodle but with all the small stature and cute face of the Cocker Spaniel. Because it’s a hybrid, the Cockapoo also has a better chance of missing out on any genetic diseases that a purebred would inherit.

Cockapoos are extremely playful, affectionate, and tend to bond to their owners quite quickly. They have a happy disposition and love spending time with their owners.

Their height can differ based on what kind of Poodle was used in the mix. Because of that, you could have smaller Cockapoos that only reach up to an owner’s knee. Yet if a standard Poodle is used, you could have a medium-sized dog on your hands.

Because smaller dogs typically live longer than larger dogs, you might want to opt for the smaller Cockapoo versions for a dog that will last a long time at your side.

The average life for a Cockapoo is 16 years.

7. Jack Russel Terrier
