The Corso's condition list is long and heavy: hip and elbow dysplasia, bloat, entropion and ectropion, cancer including bone cancer, heart disease, demodectic mange and ear infections.
Bone cancer deserves the emphasis. Osteosarcoma is a disease of large and giant breeds, it typically presents as a limp that does not resolve, and it is aggressive. A persistent lameness in a young adult Corso is an X-ray conversation, not a rest-and-see one.
The eyelid conditions are more mundane and more common than people expect. Entropion rolls the lid inward so lashes abrade the cornea; ectropion rolls it outward and leaves the eye exposed. Both are surgical fixes and both are worth asking a breeder about directly.
The Akita's burden is immune and endocrine instead: autoimmune disorders of skin, eyes and blood, hypothyroidism, progressive retinal atrophy, plus hip dysplasia.
Both are deep-chested and both carry a real gastric dilatation-volvulus risk, so both households should know the signs — unproductive retching, a distending abdomen, restlessness — and know where the nearest out-of-hours surgery is before they need it. Both breeds also have known anaesthetic sensitivities worth flagging.
