Labradors have inherited certain problems related to their health, and most notably elbow and hip dysplasia. These are mainly found in the larger dogs, so some veterinarians recommend joint supplements. Some Labradors are also in danger of
developing knee problems, and especially where the knee is dislocated.
Some Labradors are also prone to eye problems, more particularly retinal dysplasia, corneal dystrophy, cataracts, and progressive retinal atrophy. Hereditary myopathy, although rare, is an inherited disorder but should also be examined by a veterinary ophthalmologist.
Deafness and autoimmune diseases are quite rare in this breed.
Obesity is one of the biggest problems associated with the Labrador retriever. Because they like to eat continuously, they are prone to being overweight. Therefore, being the owner of the Labrador Retriever requires you to be especially diligent with regards to their diet and exercise regime. Be prepared to walk twice a day for at least half an hour each time. Another issue with Labradors is that they are quite lazy and in addition to exercise, must be stimulated, even to exercise. An overweight Labrador may experience hip and joint problems, as well as diabetes. An excellent form of exercise for a Labrador is swimming. In fact, they can swim for a couple of hours regularly to maintain a healthy weight.
Scientifically, it was proven that, after a published study in 2016, Labradors were missing all or most of the components from the POMC gene. This particular gene regulates food urges, for one. That explains the insatiable appetite the Labrador Retriever is famous for, as well as for being overweight.
