The Labrador Retriever has a slight edge with children (5/5 vs 4/5). Both breeds can do well in families, but the Labrador Retriever's friendly temperament gives it a small advantage around young kids.

These two breeds look nothing alike. The Labrador Retriever is a large breed at 25–36 kg (55–79 lbs) and 55–62 cm (22–24 in), while the Shetland Sheepdog is a small breed at just 6–12 kg (13–26 lbs) and 33–41 cm (13–16 in).

If you've spent time around both breeds, the personality gap is unmistakable. A Labrador Retriever greets the world with a friendly attitude, whereas a Shetland Sheepdog leans more toward a intelligent approach.

The Labrador Retriever needs slightly more exercise (5/5) than the Shetland Sheepdog (4/5), but neither breed is at an extreme. Both have very high to high energy levels, so the difference in your daily routine will be modest — perhaps an extra 15-20 minutes of activity for the Labrador Retriever.

The Shetland Sheepdog sheds a bit more (5/5) than the Labrador Retriever (4/5). It's not a night-and-day difference, but if you prefer a cleaner home, the Labrador Retriever has a slight edge.

Both breeds have comparable lifespans — 10–13 years for the Labrador Retriever and 12–14 years for the Shetland Sheepdog. You can expect a similar length of companionship from either breed, all else being equal.

Both breeds cost a similar amount upfront — $800–$2,000 for a Labrador Retriever versus $800–$2,000 for a Shetland Sheepdog. Where the real cost differences emerge is in ongoing expenses.

Both breeds score 5/5 for trainability — you'll have a similar experience training either one. Both are cooperative, eager learners.
