Synthesis
Which is right for you?
The Shih Tzu tends to live about 1.5 years longer on average than the German Shepherd Dog (12.8 vs 11.3 years).
Size gap is meaningful: the German Shepherd Dog is large and the Shih Tzu is small. Expect different considerations for housing, travel, and vet-care costs.
Energy levels differ significantly. German Shepherd Dogs need substantially more daily exercise than Shih Tzus — plan for 90+ active minutes per day with the German Shepherd Dog.
Shih Tzus carry a heavier breed-specific health burden (1 high-prevalence conditions vs 0 for the German Shepherd Dog). Budget for screening accordingly.
