Great Dane

Gentle, clingy and happiest leaning on whoever is nearest, the Dane is the giant that settles most easily into ordinary indoor life, provided the sofa is big. The cost to plan for is bloat: one model puts lifetime risk of gastric dilatation-volvulus above a third, so many owners pay for a preventive gastropexy at neutering. Heart disease is common too, 7 to 10 years is a realistic span, and a 60 kg adult needs an SUV or van with a large crate, not a hatchback.
