Dogs + Medical Conditions

  • Coonhound paralysis describes 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. However, 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. Severely affected dogs may need to be treated in a hospital setting but most dogs are treated at home once their diagnosis is confirmed and they are stable. The majority of dogs recover fully from coonhound paralysis.

  • 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.

  • 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.

  • 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.

  • Systemic lymphoma is a very common cancer in dogs, but the cutaneous form is quite rare. Current statistics suggest that cutaneous lymphoma accounts for only about 5% of canine lymphoma cases. The disease can present in a variety of lesions, including ulcers, nodules, red patches, and areas of hair loss and skin scaling. Because not very much is known about canine cutaneous lymphoma, there are no standard treatment protocols and the prognosis is poor.

  • Blue-green algae, also called cyanobacteria, is found in fresh and brackish water of ponds and lakes. This microscopic bacteria can also grow in backyard fountains, garden pots, bird baths, and anywhere water is stagnant. Regardless of where they are found, cyanobacteria can be dangerous.
