Life expectancy favors the Belgian Malinois: 12–14 years versus the Rottweiler's 8–10 years. For many families, those extra years together are a compelling reason to lean toward the Belgian Malinois.

You'll notice the size difference immediately. The Rottweiler stands 56–69 cm (22–27 in) tall and weighs 36–60 kg (79–132 lbs), making it considerably larger than the Belgian Malinois at 56–66 cm (22–26 in) and 25–34 kg (55–75 lbs).

The Belgian Malinois needs slightly more exercise (5/5) than the Rottweiler (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 Belgian Malinois.

Purchase prices are in the same ballpark: $1,500–$3,500 for a Belgian Malinois and $1,000–$3,000 for a Rottweiler. The initial investment won't differ dramatically between these two breeds.

Personality is where these two breeds diverge most visibly. The Belgian Malinois — originally from Belgium — has a confident, hardworking and protective disposition.

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

The Belgian Malinois has a slight training edge (5/5 vs 4/5). Both respond to positive reinforcement, but the Belgian Malinois tends to catch on a bit faster.

Both breeds score 3/5 with children, making them equally suitable for families. Proper supervision and training around children is recommended for both.
