These two breeds look nothing alike. The Rottweiler is a large breed at 36–60 kg (79–132 lbs) and 56–69 cm (22–27 in), while the Havanese is a small breed at just 3–6 kg (7–13 lbs) and 22–29 cm (9–11 in).

For families with children, the Havanese is the significantly stronger choice. With a kid-friendliness score of 5/5, the Havanese's cheerful nature makes it a natural family companion.

Life expectancy favors the Havanese: 13–15 years versus the Rottweiler's 8–10 years. For many families, those extra years together are a compelling reason to lean toward the Havanese.

If your daily schedule is packed, pay close attention here. The Rottweiler demands serious physical activity — we're talking 60-90+ minutes of vigorous exercise daily (4/5).

If you hate vacuuming, this matters. The Rottweiler's 3/5 shedding level means daily fur management is part of life.

Purchase prices are in the same ballpark: $1,000–$2,500 for a Havanese and $1,000–$3,000 for a Rottweiler. The initial investment won't differ dramatically between these two breeds.

Havaneses from the Toy group carry a cheerful, intelligent and outgoing personality, shaped by their heritage as toy dogs. Rottweilers, belonging to the Working group, are loyal, confident and protective — reflecting their own distinct breeding history.

Both breeds score 4/5 for trainability — you'll have a similar experience training either one. Both are cooperative, eager learners.
