Labradors are somewhat prone to hip and elbow dysplasia, especially the larger dogs, though not as much as some other breeds. Hip scores are recommended before breeding and often joint supplements are recommended. They also suffer from the risk of knee problems. A luxating patella is a common occurrence in the knee where the knee dislocates and goes back into place. Eye problems are also possible in some Labradors, particularly progressive retinal atrophy, cataracts, corneal dystrophy and retinal dysplasia. Dogs which are intended to be bred should be examined by a veterinary ophthalmologist for an eye score. Hereditary myopathy, a rare inherited disorder that causes a deficiency in type II muscle fibre. Symptoms include a short stilted gait or "bunny hopping," and in rare cases ventroflexion of the neck accompanied by a kyphotic posture. There is a small incidence of other conditions, such as autoimmune diseases and deafness in Labradors, either congenitally or later in life. Labradors often suffer from exercise induced collapse, a syndrome that causes hyperthermia, weakness, collapse, and disorientation after short bouts of exercise. Labradors like to eat, and without proper exercise can become obese. Laziness also contributes to this. Obesity is a serious condition and can be considered the number one nutritional problem with dogs. Therefore Labradors must be properly exercised and stimulated. A healthy Labrador can do swimming wind sprints for two hours, and should keep a very slight hourglass waist and be fit and light, rather than fat or heavy-set. Obesity can exacerbate conditions such as hip dysplasia and joint problems, and can lead to secondary diseases, including diabetes. Osteoarthritis is common in older, especially overweight, Labradors. Labradors should be walked twice a day for at least half an hour.

The median longevity of Beagles is about 12.3 years, which is a typical lifespan for a dog of their size. Weight gain can be a problem in older or sedentary dogs, which in turn can lead to heart and joint problems. Beagles may be prone to epilepsy, but this can be controlled with medication. Hypothyroidism and a number of types of dwarfism occur in Beagles. Two conditions in particular are unique to the breed:

Funny Puppy, in which the puppy is slow to develop and eventually develops weak legs, a crooked back and although normally healthy, is prone to range of illnesses

Chinese Beagle Syndrome in which the eyes are slanted and the outer toes are underdeveloped but otherwise development is as normal.

Hip dysplasia, common in Harriers and in some larger breeds, is rarely considered a problem in Beagles.

In rare cases Beagles may develop immune mediated polygenic arthritis (where the immune system attacks the joints) even at a young age. The symptoms can sometimes be relieved by steroid treatments.

Their long floppy ears can mean that the inner ear does not receive a substantial air flow or that moist air becomes trapped, and this can lead to ear infections. Beagles may also be affected by a range of eye problems; two common ophthalmic conditions in Beagles are glaucoma and corneal dystrophy. "Cherry eye", a prolapse of the gland of the third eyelid, and distichiasis, a condition in which eyelashes grow into the eye causing irritation, sometimes exist; both these conditions can be corrected with surgery. They can suffer from several types of retinal atrophy. Failure of the nasolacrimal drainage system can cause dry eye or leakage of tears onto the face.
