Older Shih Tzus are more likely to develop Cushing's Disease
Shih Tzus, typically a healthy dog breed, are prone to developing Cushing's disease in older ages. As they age, Shih Tzus become more prone to the glandular disease which causes an overproduction of corticosteriods. The disease affects a dogs overall health and needs to be treated by a veterinarian.
Causes
Cushing's disease is most commonly caused by a tumor on the pituitary gland that causes excessive ACTH. ACTH stimulates the adrenal gland, which produces corticosteroids. More rarely, a tumor on the adrenal gland causes excessive corticosteriod production.
Age and Gender
Cushing's disease usually affects dogs older than 5 years of age. For an unknown medical reason, female dogs are more likely to develop the disease.
Symptoms
The most common symptoms of Cushing's disease include excessive thirst, lethargy and weight gain. Shih Tzu's with Cushing's disease often have a pot belly.
Long-Term Complications
Over time, Cushing's disease leads to a gradual weakening of the limbs, especially the back legs. The disease also gradually weakens the skin and nervous system. Over time, dogs may develop lumps or rashes and hair loss.
Treatment
Cushing's disease needs to be treated by a veterinarian. Medicine may help improve the life expectancy of the dog, but there is no cure. Veterinarians may monitor the condition with blood tests.
Prevention
Take older Shih Tzus for semi-annual checkups with the veterinarian. At the first sign of a change in your pet's temperament, behavior or habits, take it to the doctor.
