Saints are massive dogs with massive needs. However deep chests raise bloat risk. In addition heavy bone structure stresses hips and elbows. Thick coats trap heat in summer.
Similarly lean weight helps joints. Daily calm walks beat wild sprints right after meals. However home care never replaces blood work. Your vet still needs hip exams and heart checks.
As a result you catch small shifts before a belly twist becomes a tragedy.
