Definition of Diabetes Insipidus
Diabetes insipidus is an uncommon disease in dogs that essentially causes their kidneys to excrete (or fail to reabsorb) excessive amounts of water in the urine, which makes it abnormally dilute. There are a number of different forms of this disorder, including congenital diabetes insipidus, central diabetes insipidus, nephrogenic diabetes insipidus, psychogenic diabetes insipidus and idiopathic diabetes insipidus, each of which is categorized based on its underlying cause. However, regardless of the underlying reason for their condition, all dogs with diabetes insipidus are extremely thirsty, drink excessive amounts of water and excrete large amounts of very dilute urine. Owners who notice these symptoms in their dogs should take them to a veterinarian for a physical examination and full work-up of their kidney function, which will involve routine blood work and possibly more advanced diagnostic procedures.
