Acral mutilation syndrome is the entry on the French Spaniel's list that most owners have never encountered, and it is worth understanding because it is both rare and specific.
It is an inherited sensory neuropathy. Affected dogs lose sensation in their feet, and because they cannot feel pain there they lick, chew and injure their own paws without distress. Signs appear in puppyhood, usually between three and twelve months: persistent licking of the feet, unexplained wounds, missing nails, and no reaction to injuries that should hurt.
There is a DNA test. Responsible breeders use it and can tell you the status of both parents. Because the French Spaniel population is small, asking about this specifically is more useful here than a general health assurance would be.
The rest of the list is hip dysplasia, ear infections, epilepsy and eye conditions — hip scores and eye certification being the questions to ask alongside.
The Akita's burden is autoimmune and endocrine: immune-mediated disease of skin, eyes and blood, hypothyroidism, progressive retinal atrophy, hip dysplasia and bloat as a large deep-chested breed.
