Size & Appearance
The Rottweiler is a large-sized breed, typically weighing 80–135 lbs with a lifespan of 9–10 yrs. Its build is powerful and robust with a broad chest and distinctive tan markings.
The Shih Tzu is a small-sized dog weighing 9–16 lbs and living 10–16 yrs on average. Described as small and sturdy with a round face, pushed-in nose, and flowing double coat, it presents a distinctive profile that’s immediately recognizable.
If size matters for your living situation — apartment versus house with a yard — this comparison is decisive. The Shih Tzu is the more compact option, making it ideal for apartments or smaller homes.
Temperament
The Rottweiler rates very good for trainability and is good with children. Barking tendency is low–moderate, making it generally acceptable for neighbors.
The Shih Tzu is moderate to train and excellent around kids. Its barking level is moderate — manageable overall.
Neither breed is especially stubborn, but both benefit from early socialization and positive reinforcement training starting from puppyhood.
Health & Lifespan
The Rottweiler typically lives 9–10 yrs. Hip and elbow dysplasia plus certain heart conditions are common. Cancer rates are above average for large breeds.
The Shih Tzu has an average lifespan of 10–16 yrs. Brachycephalic airway issues, luxating patella, and eye problems. Regular eye and dental care are important.
Veterinary costs vary by breed. Larger dogs and brachycephalic breeds often incur higher lifetime expenses. Always buy from health-tested breeders or adopt from a reputable rescue.
Exercise & Training
Rottweiler exercise needs: Moderate–High energy. The Rottweiler does well with 45–60 minutes of exercise daily and benefits from variety to prevent boredom.
Shih Tzu exercise needs: Low–Moderate energy. The Shih Tzu needs 30–45 minutes of moderate activity daily — short walks plus indoor play usually suffice.
Training: The Rottweiler is very good to train. Positive reinforcement works best; early socialization makes a significant difference. The Shih Tzu is moderate to train. Keep sessions short and positive; this breed responds better to patience than pressure.
Grooming
Rottweiler: Shedding is moderate, and grooming requirements are easy. Low-maintenance coat — a weekly brush and monthly bath keeps it clean and healthy.
Shih Tzu: Shedding is low, and grooming is high. Daily brushing required for full-coat Shih Tzus. A puppy cut dramatically reduces grooming time.
If shedding is a dealbreaker, the Shih Tzu will be the easier coat to live with. The Rottweiler leaves noticeably more hair around the home.
Cost
Rottweiler monthly costs: $150–$300. Larger food bills and potential for orthopedic issues. Professional training is recommended and worth the cost.
Shih Tzu monthly costs: $100–$250. Regular grooming is the primary ongoing cost. Otherwise a moderate expense for a small dog.
Puppy prices also vary significantly — popular or trendy breeds can command $2,000–$5,000+ from reputable breeders. Consider adoption as an alternative; both breeds have dedicated rescue organizations.
