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 refers to any abnormality of the structure or function of the heart. Most dogs display no clinical signs until heart disease is advanced, although it may be detected earlier, if your veterinarian hears a heart murmur during a physical examination. This handout outlines types of heart disease and summarizes signs, diagnosis, and treatment options.

A heart murmur is an abnormal heart sound caused by turbulent blood flow. This article explains the common causes of heart murmurs in dogs, how they are diagnosed, and when further testing may be recommended. Learn how the underlying cause influences treatment and prognosis.

Heartworm disease is a serious and potentially fatal disease caused by a parasite transmitted to dogs by mosquitos. Heartworm larvae migrate through the dog’s bloodstream to the heart and adjacent blood vessels, where they mature into adult heartworms. This handout explains the disease and outlines signs, diagnosis, treatment and prevention.

Osteoarthritis (OA) is a progressive, degenerative disease that worsens over time. This handout discusses ways you can help your dog deal with OA. In addition to medications that may be prescribed by your veterinarian, other treatment options are outlined, such as weight loss, exercise, and complementary therapies such as chiropractic and physiotherapy.

Hemophilia A and B are inherited clotting disorders that cause problems with blood clotting, and make it difficult to control bleeding. Dogs are often diagnosed based on signs of excessive bleeding. Hemophilia is genetic, so it is vital to screen potential breeding animals. Carriers do not exhibit symptoms, but they should not be used in breeding programs.

Hepatic encephalopathy is a neurological 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. This handout outlines common causes, signs, diagnosis, and treatment options.
-
Hepatic microvascular dysplasia is an inherited abnormality of the liver where microscopic blood vessels in the liver are underdeveloped or absent, resulting in decreased blood flow to the liver. As a result, the liver is less capable of processing toxins or producing the vital proteins needed for good health.

Hiatal hernia refers to the protrusion of the abdominal contents into the chest cavity through the esophageal hiatus of the diaphragm. In most veterinary patients hiatal hernias appear to be congenital. Diagnosis is based on medical history, clinical signs, and X-rays (radiographs).

The most common cause of hip dislocation is blunt force trauma (a fall or automobile injury). Hip dysplasia, a common developmental disorder in which the hip joint does not form properly, can also predispose a dog to hip dislocation. Most dogs with a hip dislocation will have severe hind limb lameness and may not be able to put any weight on the affected limb.
