Globoid-cell leukodystrophy, also called Krabbe disease or lysosomal storage disease, is a rare disease caused by a mutation in a dog’s DNA. It results in abnormal processing and storage of an enzyme critical for producing myelin, the substance that coats and protects the nerves throughout the brain and spinal cord. Clinical signs emerge at an early age, including tremors, muscle weakness, and loss of control of the limbs. Most dogs must be euthanized due to their neuromuscular decline about two to six months after the onset of clinical signs.

Heart disease is more common in dogs than in cats. It can be due to congenital defects or adult-onset disease. The two most common types of adult heart disease are mitral regurgitation (valve disease) and dilated cardiomyopathy or DCM (heart muscle disease). Diagnosis involves X-rays, ECG, and echocardiography. Treatment depends on the cause of heart disease.

A heart murmur is an abnormal sound that originates from the heart valves and can be heard with a stethoscope skillfully placed over the heart valves.

Hemophilia A and B are clotting disorders involving a deficiency of a specific clotting factor (A: Factor VIII, B: Factor IX) needed for appropriate homeostasis. They are caused by a sex-linked recessive genetic mutation. Affected dogs will show inappropriate hemorrhage including bruising, lameness induced by bleeding into joints and body cavity hemorrhage. It can be diagnosed with a slow APTT and demonstrating low levels of the factor involved. Hemophilia A is more common than B and is generally, more severe. Because it is sex-linked recessive, males are more likely to be affected than females but females still act as carriers, so genetic screening is important prior to breeding to prevent this disease.

Hepatic encephalopathy is a neurologic condition in cats and dogs that is caused by an underlying liver condition. It can cause lethargy, seizures, problems with balance and coordination, and coma. Common causes, methods to diagnose the condition, and its treatment options are explained in this handout.

This handout explains hepatic microvascular dysplasia, a condition where microscopic blood vessels within the liver are underdeveloped or absent, resulting in decreased blood flow to the liver. As a result, the liver is less capable of dealing with toxins or producing the vital proteins needed for good health. Methods to diagnose the condition and its treatment options are also explained.

The most common cause of hip dislocation is blunt force trauma such as a fall or an automobile injury. Most dogs with a hip dislocation will have severe hind limb lameness and pain and may not be able to put any weight on the affected limb. A diagnostic radiograph will show the direction of dislocation and whether a fracture of any part of the hip joint has occurred. In many cases, it is possible to replace the femoral head in the acetabulum by manipulation under general anesthesia. If the femoral head has been successfully replaced and the correct post-operative treatment has been adhered to, it is unlikely that the hip will dislocate again.

Hygromas are fluid-filled non-painful swellings that develop suddenly over a bony prominence. They are the body’s reaction to repetitive trauma and usually a result of laying too frequently on hard surfaces. The best treatment is to ensure the prominence affected is well padded to allow the hygroma to recede. This can be accomplished by appropriate padding in the dog’s living quarters and by directly padding the affected area if possible. Rarely, hygromas become infected requiring antibiotics. Very few will need surgery to manage them. This would be recommended on an individual case basis.

Hyperlipidemia refers to elevated levels of lipids (fats) in the bloodstream and can be due to several causes. Often times there are no clinical signs. Hyperlipidemia is confirmed using a 12-18 hours fasting sample. The pet's medical history and a search for an underlying cause is important for its treatment. If no underlying cause is found, your pet will need to start eating a low-fat, high-fiber diets, and may be started on the appropriate medications and supplements.
