Shelties are wired to herd and bark at anything that moves, including running kids, cyclists, and the doorbell, and that is the breed working as designed, not a training failure you can fully eliminate.
13.4years, median
0.9 years above the all-dog median of 12.5.
Measured, not estimated: the middle age at death across 584,734 UK dogs, 284,734 of them deceased. Based on 2,698 dogs of this breed. 95% confidence interval 13.1 to 13.6 years. Half lived longer than this, half did not. UK dogs, so treat it as the best available figure rather than a promise about yours.
In the same study, small breeds as a group had a median of 12.7 years and long-muzzled breeds 12.1. This breed is small and long-muzzled.
McMillan et al. 2024, Scientific Reports 14:531 — open access · CC BY 4.0American Shetland Sheepdog Association sets the tests a Shetland Sheepdog needs for a CHIC number in the OFA's open database. A CHIC number means the tests were done and the results are public. It does not mean the dog passed them: ask for the results for both parents, or look them up yourself on ofa.org.
When to spay or neuter a Shetland Sheepdog: the UC Davis study of 35 breeds has a suggested guideline for the breed. For males it is any age. For females, 2 years or later. The spay and neuter page has the numbers behind it and what the guidelines say for a dog this size.

Shelties are smart, biddable, and easy to train, but that intelligence needs an outlet, daily exercise plus mental work like obedience or agility, or it comes out as barking and herding behavior aimed at your family. The coat looks glamorous but sheds heavily and mats without twice-weekly brushing, and many Shelties are naturally wary of strangers and loud noises, so early socialization matters more than the gentle-collie reputation suggests.
