Quick answer
Should I get a Great Dane or Mastiff?
Great Danes are usually taller, leggier, and more visibly goofy. Mastiffs are heavier, denser, and often more guardian-like, but both are giant breeds where cost, space, and health planning matter more than looks.
The best choice depends less on looks and more on daily rhythm: activity tolerance, training appetite, coat cleanup, heat or cold limits, and how much health-cost uncertainty your household can absorb.

Run the decision through your real constraints: kids, other pets, apartment rules, climate, alone time, shedding tolerance, and whether anyone in the home needs allergy or mobility accommodations.
