Histoplasmosis is an infection caused by histoplasma, a fungus found in moist soils and especially prevalent around the Ohio, Mississippi, Missouri, and St. Lawrence rivers, as well as the southern Great Lakes and Alberta. Fungal spores are inhaled or ingested and cause infection in many sites including the lungs, gastrointestinal tract, eyes, joints, and spleen. This handout outlines signs, diagnosis, treatment, and prognosis. Histoplasmosis is transmissible to humans, especially if they are immunocompromised.

Urticaria, or hives, is a skin condition characterized by raised red skin welts caused by direct contact with a substance that causes an allergic reaction. These substances include insect bites, food, pollens, molds, vaccinations, and medications. If the swelling progresses to the throat, breathing can be compromised and result in a medical emergency called anaphylaxis. Injectable antihistamines and corticosteroids usually bring about a dramatic improvement, sometimes in as little as a few minutes.

Horner's syndrome is a common neurological disorder of the eye and facial muscles and can occur suddenly. Horner's syndrome is caused by dysfunction of the sympathetic nerves of the eyes and surrounding facial muscles. It may be due to an injury such as a bite wound or blunt trauma, a tumor, intervertebral disc disease, or middle or inner ear disease. If an underlying cause can be identified, treatments will target that issue; however, many cases spontaneously recover after some time.

Canine hot spots are red, inflamed skin lesions that appear quickly, ooze, and may contain pus. They are the result of a dog excessively scratching, licking, or chewing at an itch. There are several possible underlying causes of the itch and it is crucial to determine what it is to successfully treat the problem. This handout explains these possible causes and the treatment(s) required to resolve them.

Pain can be difficult to detect in older dogs. It is important for dog owners to recognize subtle signs of pain in their dog, such as slowing down on walks, unwillingness to play, reluctance to sit or stand, limping or weight shifting, and sensitivity to touch on being picked up. If any of these behaviors are observed, your dog should be evaluated by your veterinarian and a pain management plan devised.

Hydrocephalus is an excess of cerebrospinal fluid (CSF) that has leaked inside the skull, leading to brain swelling. There are two main types of hydrocephalus in dogs: congenital and acquired. Small, miniature, toy, and brachycephalic breeds seem to be more affected. Signs, diagnosis, and treatment are outlined. Your veterinarian will discuss your pet's prognosis and treatment options based on its individual condition.

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.

The term hypocalcemia is used when the level of calcium in the blood is lower than normal. Calcium levels are controlled by a pair of parathyroid glands. Low calcium levels are associated with a number of serious disorders including antifreeze poisoning, inflammation of the pancreas, kidney failure, and parathyroid gland failure. In nursing female dogs, heavy milk production can lead to hypocalcemia and may result in seizures. Pets with hypocalcemia may show signs of muscle twitching, loss of appetite, weakness, and listlessness. Your veterinarian will perform diagnostic tests which may include testing total calcium, ionized calcium, albumin, and parathyroid hormone levels. Primary hypoparathyroidism can be managed with a medication plus nutritional supplements containing vitamin D and calcium.
