Cushing's Disease in Schnauzers

Miniature schnauzers are at risk for developing Cushing's disease.

Schnauzers, especially miniature Schnauzers, are at risk for developing autoimmune and hormonal disorders. One hormonal disorder found in schnauzers is Cushing's disease. A veterinarian can diagnose the disorder and recommend treatment.

Cushing's Disease

Cushing's disease, or hyperadrenocorticism, occurs when a dog's adrenal glands produce too much cortisol, a hormone. This hormonal disorder is relatively common in miniature schnauzers. It usually develops in dogs over the age of six. It can be triggered by a problem with a schnauzer's pituitary gland, according to Washington State University.

Symptoms

A miniature schnauzer with Cushing's disease will experience symptoms including an increased appetite. Many dogs also develop hematomas and if they are injured, their wounds heal slowly. A schnauzer's coat can change color, growing lighter as its hair thins and its skin becomes scaly. Other symptoms include increased drinking and urination and a pot-bellied appearance.

Diagnosis

In order to diagnose Cushing's disease in a miniature schnauzer, a veterinarian will perform a physical exam and review a dog's medical history. Blood tests can reveal increased white blood cell counts and high sugar levels in a dog's blood. Urine tests can reveal diluted urine. While there is no single test for Cushing's disease, these results taken together indicate that a dog is sick.

Treatment

Cushing's disease in Schnauzers is usually treated with medication that is required for life. The most common medications prescribed for Cushing's disease in dogs are Mitotane and Trilostane. At first, the medications will need to be given daily, but after a few weeks the dog will only need medication once or twice a week. The medications can cause side effects, so an owner should remain in contact with the veterinarian to avoid adverse effects.

Considerations

After a miniature schnauzer is treated for Cushing's disease, its eating and drinking habits will return to normal in a few weeks. It could take as long as a few months for its hair to grow back and return to its normal appearance. While Cushing's disease can only be managed, not cured, the medication can help a miniature schnauzer maintain its quality of life for years.
