Great Dane vs Saint Bernard

A dog this size usually only gets about 7 to 10 years with you, and its deep chest puts it at real risk of sudden, fatal stomach bloat (GDV) that breeders rarely mention at pickup.

A dog this size shouldn't be dying at 8 to 10 years old, but that's the typical lifespan for a Saint Bernard — add in constant drooling, real bloat risk, and a genuine chance of four-figure vet bills for hip dysplasia or bone cancer, and the 'gentle giant' image sold at pickup rarely matches the true lifetime cost.
