All dogs can get all dog diseases. That said, Labradors generally have phenomenal appetites and are prone to becoming overweight or obese. This can not only shorten their lifespan, but may also make other diseases worse. Based on research studies, some conditions that Labradors are predisposed to include, but are not limited to: allergies (which usually manifest as skin issues), some heart conditions, chronic hepatitis, diabetes mellitus, hypothyroidism, cranial cruciate ligament rupture, elbow and hip dysplasia, some muscle disorders, epilepsy, some kinds of cancer, juvenile onset cataracts, entropion, ectopic ureters, laryngeal paralysis, and low B12 levels. Swimming-related conditions like limber tail (sprained tail from swimming or wagging too much) are also possible.
