What Is the Lifespan of a Cocker Spaniel?

Cocker Spaniels have a relatively long lifespan and can live anywhere from 12 to 15 years, according to Dog Breed Info. While Cocker Spaniels are a relatively hardy breed, owner's should watch out for issues such as liver disease.

Like any animal, Cocker Spaniels live the longest when properly cared for. Cocker Spaniels need adequate exercise on a daily basis. Cocker Spaniels tend to gain weight easily and require a strict diet, according to Rocky Mountain Cocker Rescue. Typically, this breed does well on a raw diet that is low in wheat. Higher end dog foods can also help keep weight in check.
