The lifespan difference is significant. Miniature American Shepherds live 12–15 years on average, while Labrador Retrievers live 10–13 years.

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.

You'll notice the size difference immediately. The Labrador Retriever stands 55–62 cm (22–24 in) tall and weighs 25–36 kg (55–79 lbs), making it considerably larger than the Miniature American Shepherd at 33–46 cm (13–18 in) and 9–18 kg (20–40 lbs).

The Labrador Retriever needs slightly more exercise (5/5) than the Miniature American Shepherd (4/5), but neither breed is at an extreme. Both have very high to very 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.

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

Both breeds shed at the same rate (4/5), so fur management will be identical for either choice. Budget for a good robot vacuum.

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 Miniature American Shepherd leans more toward a intelligent approach.

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