How Diabetes Insipidus Affects Dogs
Diabetes insipidus is not common in companion animals. However, because the primary clinical sign is production and excretion of abnormally large amounts of urine, when it does happen, owners tend to take notice. Although there are a number of things that can cause or contribute to diabetes insipitus, the symptoms in domestic dogs typically are the same.
Symptoms of Diabetes Insipidus
Dogs with diabetes insipidus may develop one or more of the following symptoms:
- Passage of abnormally large amounts of urine (polyuria)
- Passage of abnormally dilute urine (urine with low specific gravity)
- Extreme thirst
- Abnormally increased water intake (polydipsia)
- Inappropriate elimination (loss of housetraining; urinating in inappropriate places; may be perceived by owners as incontinence)
- Loss of coordination (ataxia)
Dogs at Increased Risk
There is no breed, age or gender predisposition in companion dogs for the development of diabetes insipidus. However, dogs with congenital or nephrogenic diabetes insipidus are frequently diagnosed by 6 to 12 months of age, while dogs with central diabetes insipidus (especially if it is related to pituitary tumors) are usually not diagnosed until they are quite a bit older – on average, over 5 years of age.
