These two breeds look nothing alike. The Great Dane is a giant breed at 45–90 kg (99–198 lbs) and 71–86 cm (28–34 in), while the French Bulldog is a small breed at just 8–13 kg (18–29 lbs) and 28–33 cm (11–13 in).

The upfront cost gap is substantial. A French Bulldog puppy runs $1,500–$5,000, while a Great Dane is $1,000–$3,000.

Life expectancy favors the French Bulldog: 10–12 years versus the Great Dane's 7–10 years. For many families, those extra years together are a compelling reason to lean toward the French Bulldog.

The Great Dane needs slightly more exercise (3/5) than the French Bulldog (2/5), but neither breed is at an extreme. Both have moderate to moderate energy levels, so the difference in your daily routine will be modest — perhaps an extra 15-20 minutes of activity for the Great Dane.

The Great Dane sheds a bit more (3/5) than the French Bulldog (2/5). It's not a night-and-day difference, but if you prefer a cleaner home, the French Bulldog has a slight edge.

Both breeds score 4/5 with children, making them equally suitable for families. Either breed would make an excellent family dog.

Personality is where these two breeds diverge most visibly. The French Bulldog — originally from France — has a playful, adaptable and affectionate disposition.

Both breeds score 3/5 for trainability — you'll have a similar experience training either one. Both are moderately responsive and benefit from consistent training sessions.
