Arthritis, or degenerative joint disease, is a condition in which one or more joints in the body deteriorate. Arthritis may occur as a result of trauma, natural aging, or syndromes called dysplasias in which the joints do not develop properly.

Diabetes mellitus (known simply as diabetes) is a serious disease of dogs. The main characteristic of diabetes is an inability to control the level of sugar in the blood. This leads to chronically high blood sugar levels, which in turn lead to the symptoms of the disease.
Management of diabetes in dogs is challenging but possible. With proper treatment, many diabetic dogs lead essentially normal lives. However, without treatment the disease inevitably leads to serious complications.
Damaged toenails are very common, especially in active dogs. Most nail injuries occur as a result of a nail catching or snagging on plant matter, carpet, or other material while the dog is running.
Damaged toenails are extremely painful at the moment of injury. In many cases, pain will persist until the damaged portion of the nail is removed by a veterinarian. However, the vast majority of dogs with injured nails make complete recoveries.
Heart failure is a condition in which the heart is unable to circulate blood throughout the body in a normal fashion. In dogs, two types of heart disease may lead to heart failure. The most common type of heart disease in dogs is caused by a malfunctioning (or leaky) valve in the heart. Another form of heart disease, called cardiomyopathy, is caused by a defect in the muscles of the heart. Although these two syndromes develop in different fashions, both often lead to the same result: heart failure.
Kennel cough, also known as infectious tracheobronchitis (ITB), is a contagious disease of dogs. A large number of organisms are believed to play a role in the syndrome. Kennel cough most often is caused by simultaneous infection with a mild respiratory virus (there are many such viruses) in combination with a bacteria called Bordetella bronchiseptica. The infection usually is limited to the windpipe (trachea) and major air passages in the lungs.

Dental disease is by far the most common major health problem of cats and dogs. Despite its name, dental disease does not merely affect the teeth and mouth. Dental disease impacts the entire body, with serious consequences for health, longevity, and well-being.
Obesity is a syndrome in which the amount of excess body fat an individual carries is great enough to cause harm to health and well-being. Obesity is a debilitating syndrome that is linked to a number of serious health consequences for dogs.
A number of factors play a role in the development of obesity in dogs. However, the root cause of obesity is the consumption of more calories than the body needs.
Primarily dogs; rarely cats
Marijuana intoxication may occur in pets that have access to marijuana plants, dried portions of the plants, or foodstuffs containing marijuana.
Cats and dogs of any age.
Ear infections are common and painful problems for pets. In cats and dogs, ear infections typically are opportunistic and not contagious. They often occur when the ear’s immune system is disrupted by allergies, moisture, poor air circulation, or diseases such as feline AIDS. Under these conditions, bacteria and yeast that normally live harmlessly in the ear are able to proliferate to the point of infection.
