Coonhound paralysis is a sudden inflammation of multiple nerve roots and peripheral nerves in dogs, and occasionally cats. It can be caused by an immune reaction to raccoon saliva. It can also occur in dogs who have not encountered a raccoon. In this case, it is called acute idiopathic polyradiculoneuritis, and its cause is often unknown. Dogs with coonhound paralysis start out with a stiff-legged gait that rapidly progresses to paralysis of all four legs. Good nursing care is essential for recovery.

Corkscrew tail, also known as screw tail or ingrown tail, is a vertebral malformation that commonly occurs in certain dog breeds. Corkscrew tail is commonly observed in English Bulldogs, Pugs, Boston Terriers, and French Bulldogs, although it may also occur in other breeds. Corkscrew tail is an inherited condition. There is nothing that you can do to prevent your dog from developing corkscrew tail, but there are measures breeders can take to reduce the incidence of corkscrew tail in their litters.

Corneal dystrophy is a term used to describe several conditions that occur in dogs and cause the corneas to become opaque. There are three major categories of corneal dystrophy: epithelial, stromal, and endothelial. Each is named by the anatomic location of the abnormal tissue and opacity.

Corneal lipidosis is an accumulation of fatty substances within the cornea. This is caused by genetics (corneal dystrophy), eye inflammation (corneal degeneration), or by an increase in circulating lipids in the body (hyperlipidemia). Visually, lipidosis appears as a sparkly or shiny area of the cornea. It is diagnosed by a thorough eye exam, bloodwork, and patient history. Treatment and prognosis will depend on the cause and may include treatment of underlying inflammatory conditions of the eye, or systemic treatment of elevated lipid blood levels.

Ulcerative keratitis is a kind of inflammation that occurs in the cornea of the eye with a corneal ulcer. Some breeds seem to develop them more commonly, particularly breeds with short muzzles and prominent eyes like pugs and Boston terriers. There are many potential causes of ulcerative keratitis, including trauma, infection, and abnormal tear production. Antibiotic ointment or drops will be prescribed, and it is important to prevent additional trauma to the cornea. Superficial corneal ulcers typically heal within 5 to 7 days.

The cornea is the transparent, shiny membrane that makes up the front of the eyeball. With a corneal ulcer, fluid is absorbed from the tears into the stroma, giving a cloudy appearance to the eye. The most common cause of a corneal ulcer is trauma. Less common causes of corneal ulcers include bacterial infections, viral infections, and other diseases.

Cryptosporidium is a species of single-celled parasite that can infect your dog through the gastrointestinal tract. Clinical signs such as diarrhea and weight loss may only be seen in immunosuppressed patients, including puppies. These patients may need supportive care and other treatment to control disease. Certain Cryptosporidium species can be spread between pets and humans, making this parasite zoonotic.

Cushing's disease is a condition in which the adrenal glands overproduce certain hormones. There are three types of Cushing's disease, each of which has a different cause. The most common cause of Cushing's disease is a pituitary gland tumor. Cushing's disease may also be the result of a benign or malignant tumor of the adrenal gland itself, or may be caused from the excessive administration of an oral or injectable steroid. Clinical signs, treatment, and prognosis are discussed.

Cushing's disease, or hyperadrenocorticism, is the overproduction of cortisol hormone by a dog's body. The clinical signs of Cushing's disease are similar, regardless of the underlying cause of the disease. However, it is essential to identify the type of Cushing's disease as the treatment and prognosis differ slightly depending upon the form of the disease.

Treatment for Cushing’s disease using mitotane involves two phases: initiating phase and maintenance phase. Monitoring your dog’s food and water intake is very important. This handout provides detailed treatment instructions for dogs prescribed mitotane. Follow your veterinarian’s instructions carefully and report changes in your dog’s behavior to your veterinarian.
