Hydrocortisone ophthalmic is a topical steroid medication used to treat surface inflammation in the conjunctiva of the eye. It is used to treat inflammatory eye conditions in cats and dogs. It may be used “off label” or “extra label” to treat eye conditions in animals other than cats or dogs. Hydrocortisone ophthalmic comes in ointment and liquid drop form. Avoid use in animals with viral or fungal infections, corneal ulceration, and birds.

Do not use in pets that are allergic to it, or in pregnant pets unless absolutely necessary. If a negative reaction occurs, please call your veterinary office.

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.

The term hypercalcemia is used when the level of calcium in the blood is higher than normal. Calcium levels are controlled by a pair of parathyroid glands. High calcium levels may signal the presence of serious underlying disease including kidney failure, adrenal gland failure, a parathyroid gland tumor, and some types of cancer. Pets with hypercalcemia may show signs of weakness, listlessness, increased drinking and urination, and loss of appetite. Your veterinarian will perform diagnostic tests which may include total calcium, ionized calcium, albumin, and parathyroid hormone levels.

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.

This handout discusses the concept of hypoallergenic dogs. These breeds are meant to create less allergic reactions in people that suffer from dog allergies. Humans sometimes react to the proteins found in dog saliva and dander. Precautions to take when trying to reduce your exposure to these allergens are highlighted. As well, breeds that tend to be less reactive to dog allergy sufferers are discussed.

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.

Hypokalemia is a term that refers to a low blood concentration of potassium. Potassium is an important electrolyte within the body and is vital for the normal function of muscles and nerves. Mild to moderate hypokalemia often does not cause clinical sigs, but severe hypokalemia can result in generalized muscle weakness, lack of appetite, and some dogs may become constipated. The underlying cause of hypokalemia is often chronic kidney failure. Hypokalemia and its associated clinical signs may be quickly corrected by potassium supplementation. Depending on the cause, it may be necessary to continue supplementing potassium permanently.
