How Long Do Jack Russell Terriers Live?

Jack Russell Terriers are lauded for their long life spans. Jack Russell Terriers can live up to 15 years and longer under the right conditions, according to the Jack Russell Terrier Club of America.

Jack Russell Terriers live very active lives as hunting dogs and are extremely energetic, says the Jack Russell Terrier Club of America. The Club also states that the dogs of this breed are very intelligent, but require discipline and training. When properly trained, these dogs can stay active for most of their lifetime. However, those that receive improper training or supervision tend not to live out their expected life spans.
