A focal seizure refers to an abnormal electrical activity surge confined to a specific area of the brain. Fly-biting seizures are a type of focal seizure in which a dog snaps at the air like she is biting at invisible flies. Although the only way to definitively determine that fly-biting and other suspected focal seizures are caused by seizure activity is through an electroencephalogram (EEG), this test is often impractical due to the unpredictable nature of the seizures. The same anti-epileptic medications used for generalized seizures are typically used in managing focal seizures.

Follicular conjunctivitis is an eye condition that primarily affects young dogs, under 18 months of age. Follicular conjunctivitis is often caused by allergens, such as dust, grass, and weeds. Mild cases of follicular conjunctivitis do not require treatment. If your dog’s eye is uncomfortable, treatment may include saline rinses, topical steroids, and possible debridement.

Gastroesophageal reflux disease (GERD) is a chronic condition in which stomach acid flows from the stomach to the esophagus. In dogs with GERD, stomach acid passes through the lower esophageal sphincter and enters the esophagus. Possible signs associated with GERD include decreased appetite, difficulty swallowing, licking the lips, change in bark, chronic cough, appearance of generalized discomfort, pacing, or restlessness at night. Gastrointestinal reflux disease is often diagnosed on the basis of endoscopy. There are a number of different treatments for GERD. Most dogs require a combination of treatments, each of which addresses the problem differently. Most dogs experience a rapid improvement in clinical signs with treatment.

A gastropexy is a surgical procedure that is sometimes performed in large-breed dogs to prevent gastric dilatation and volvulus (GDV), also known as bloat – a life-threatening condition. This handout explains how the procedure works, how it is used preventatively and in emergency situations, risk factors, and post-operative care.

Gingival hyperplasia is the abnormal growth of excessive gum tissue. The gums may appear reddened or inflamed and may become so enlarged that it is difficult to visualize the teeth. In some cases, gingival hyperplasia may be localized to specific areas and its appearance may mimic the appearance of a mass or tumor. Gingival hyperplasia is most commonly treated with the surgical removal of the excessive proliferative tissue, referred to as gingivoplasty. Although it results in a significant improvement in clinical signs, gingivoplasty does not typically cure the condition.

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.

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.
