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.

Ferrets can be affected by a variety of conditions causing problems with the stomach and intestinal tract. Certain bacteria may cause diarrhea or gastritis. Intestinal foreign bodies often cause a complete blockage of the intestinal tract. Some conditions may be treated with medication while others require surgical intervention.

Gastrointestinal endoscopy uses a flexible tube with a camera or viewing port to inspect the esophagus, stomach, proximal small intestine, or colon for evidence of disease-causing clinical signs characteristic of gastrointestinal disease. Foreign bodies can often be retrieved. Biopsies are taken of abnormal and normal tissue, as not all conditions cause gross changes to the stomach or intestinal surface. The endoscope cannot reach all areas of the small intestine, so other tests may be needed to diagnose disease in this area. Endoscopic pinch biopsies are not full thickness so if diagnosis is not achieved with endoscopic biopsies, additional testing including surgical biopsies may be needed. 12-18 hours fasting and enemas are required prior to endoscopy depending on the area being studied.

Rabbits that are not eating may have developed gastrointestinal (GI) stasis. GI stasis may be caused by a physiologic change in bacteria or by one of several other conditions such as E. cuniculi. Supportive treatment either in or out of the hospital will be prescribed for a rabbit with GI stasis. Prevention steps are discussed. Have your rabbit checked regularly by a veterinarian who can monitor for the occurrence of other underlying diseases that may contribute to the development of GI stasis.

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.

Glaucoma is a disease of the eye in which the pressure within the eye, called intraocular pressure (IOP), is increased. Glaucoma is caused by inadequate drainage of aqueous fluid. Glaucoma is classified as primary or secondary. High intraocular pressure causes damage to occur in the retina and the optic nerve. Blindness can occur very quickly unless the increased IOP is reduced. Analgesics to control the pain and medications that decrease fluid production and promote drainage are often prescribed to treat glaucoma. The prognosis depends to a degree upon the underlying cause of the glaucoma.

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.
