Phosphofructokinase deficiency is the entry on the Springer's list most owners have never heard of, and it is the one with the cleanest answer.
It is an inherited enzyme deficiency that leaves red blood cells fragile under stress. Affected dogs can have episodes of red or brown urine, weakness, fever and pale gums after hard exercise, excitement or panting in heat — precisely the situations a working spaniel is in constantly. There is a DNA test, and no reason for a breeder not to have used it. Ask for the result by name.
Hip and elbow dysplasia and progressive retinal atrophy complete the list, with hip scores and eye certification the corresponding questions.
The Akita's burden is autoimmune and endocrine: immune-mediated disease of skin, eyes and blood, hypothyroidism, progressive retinal atrophy, hip dysplasia and bloat.
On money the Springer is cheaper at $100–$200 a month against $110–$240, and $1,400–$2,900 against $1,700–$3,200 in the first year — though grooming and recurring ear treatment narrow that in practice.
Lifespan runs 12 to 14 years against 10 to 13.
