Beyond obesity, the Labrador carries hip and elbow dysplasia, cruciate ligament injuries, progressive retinal atrophy, cataracts, ear infections, epilepsy, hypothyroidism, exercise-induced collapse, heart disease, cancer and bloat.
Two of those have DNA tests worth asking about by name: progressive retinal atrophy and exercise-induced collapse, in which an affected dog collapses after five to twenty minutes of intense excited exercise and usually recovers within half an hour. Hip and elbow scores should be produced as numbers, not described.
Ear care is routine rather than optional — drop ears on a dog that swims constantly means drying them every time.
On money the two are close: $100–$200 a month against $110–$240, and $1,800–$3,000 against $1,700–$3,200 in the first year. Grooming favours the Labrador at 2/5 against 3/5, though it sheds heavily year-round at 4/5 where the Akita concentrates 5/5 shedding into two annual periods.
Lifespan runs 10 to 13 years against 10 to 12.
