Synthesis
Which is right for you?
The Miniature Schnauzer tends to live about 2.7 years longer on average than the Great Dane (13.3 vs 10.6 years).
Size gap is meaningful: the Great Dane is giant and the Miniature Schnauzer is small. Expect different considerations for housing, travel, and vet-care costs.
Energy levels are close, with a slight edge to the Great Dane (60 min/day of directed exercise).
Miniature Schnauzers tend to pick up obedience work faster (5/5 trainability). Miniature Schnauzers rate higher for household-with-kids compatibility (5/5).
