You'll notice the size difference immediately. The Great Dane stands 71–86 cm (28–34 in) tall and weighs 45–90 kg (99–198 lbs), making it considerably larger than the Labrador Retriever at 55–62 cm (22–24 in) and 25–36 kg (55–79 lbs).

Life expectancy favors the Labrador Retriever: 10–13 years versus the Great Dane's 7–10 years. For many families, those extra years together are a compelling reason to lean toward the Labrador Retriever.

Purchase prices are in the same ballpark: $1,000–$3,000 for a Great Dane and $800–$2,000 for a Labrador Retriever. The initial investment won't differ dramatically between these two breeds.

Great Danes from the Working group carry a friendly, patient and dependable personality, shaped by their heritage as working dogs. Labrador Retrievers, belonging to the Sporting group, are friendly, outgoing and active — reflecting their own distinct breeding history.

If your daily schedule is packed, pay close attention here. The Labrador Retriever demands serious physical activity — we're talking 60-90+ minutes of vigorous exercise daily (5/5).

If you're a first-time dog owner, this is critical. The Labrador Retriever's trainability score of 5/5 means it responds well to basic positive reinforcement and learns household rules fast.

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.

The Labrador Retriever sheds a bit more (4/5) than the Great Dane (3/5). It's not a night-and-day difference, but if you prefer a cleaner home, the Great Dane has a slight edge.
