Dogs can get diabetes insipidus, but it is fairly rare. This condition occurs when the body does not produce enough antidiuretic hormone (ADH). ADH helps the body to reabsorb water, so without it, dogs (and people) tend to urinate a lot and drink a lot of water.
Diabetes insipidus can be caused by a number of things, including certain medications, head injuries, brain tumors, and other medical conditions. Treatment for diabetes insipidus usually involves replacing the missing ADH with medication.
What are the Symptoms of Diabetes Insipidus in Dogs?
There are a few different types of diabetes insipidus (DI) that can affect dogs, but the most common form is central DI. This occurs when there is a problem with the pituitary gland, which is responsible for producing vasopressin (also known as antidiuretic hormone or ADH).
Vasopressin helps regulate water balance in the body by telling the kidneys how much water to reabsorb back into circulation. Without enough vasopressin, too much water is excreted in urine and dogs become excessively thirsty and urinate more frequently.
Symptoms of DI can vary depending on how much vasopressin is being produced. If levels are only slightly decreased, dogs may only be mildly thirsty and urinate a bit more than normal. More severe cases can lead to excessive thirst and drinking, as well as increased urination (up to 20 times per day or more).
This can obviously lead to dehydration if not managed properly. In very rare cases, DI can also cause seizures due to extreme dehydration. If you think your dog might have diabetes insipidus, it’s important to see a veterinarian for diagnosis and treatment.
Treatment will usually involve daily injections or oral medication designed to replace the missing vasopressin. With proper treatment, most dogs with DI can live relatively normal lives.
How Do You Test for Diabetes Insipidus in Dogs?
There are a few different ways to test for diabetes insipidus in dogs. The most common way is to measure the dog’s blood sugar levels. If they are consistently high, it may be indicative of diabetes insipidus.
Another way to test for diabetes insipidus is to measure the dog’s urine output. If it is excessive, it may be indicative of diabetes insipidus. Finally, if the dog exhibits signs of dehydration, such as excessive thirst or urination, weight loss, or lethargy, it may also be indicative of diabetes insipidus.
What are the Initial Signs of Diabetes Insipidus?
Diabetes insipidus is a medical condition caused by an insufficient level of antidiuretic hormone (ADH) in the body. ADH is responsible for regulating water balance in the body by controlling the amount of water that is excreted in urine.
When there is not enough ADH present, the body cannot properly regulate water balance, leading to excessive urination and dehydration.
The most common symptom of diabetes insipidus is polyuria, or excessive urination. Other symptoms can include thirst, dehydration, weight loss, and fatigue.
In severe cases, coma and death can occur if untreated. If you think you may have diabetes insipidus, it is important to see a doctor right away so that proper treatment can be started.

Diabetes Insipidus in Dogs Diet
If your dog has been diagnosed with diabetes insipidus, you may be wondering what the best diet is for them. Here are some things to keep in mind when choosing a food for your diabetic dog.
1. Avoid foods with high sugar content. Dogs with diabetes insipidus need to maintain a consistent blood sugar level, so sugary foods can cause fluctuations that can be dangerous. Instead, opt for complex carbohydrates like brown rice or oats which will provide a more steady source of energy.
2. Make sure the food is high in protein. This is important for all dogs, but especially those with diabetes insipidus as protein helps to regulate blood sugar levels. A good quality dog food will have meat as the first ingredient listed on the label.
3. Avoid processed foods and fillers. These ingredients can be hard to digest and can also affect blood sugar levels negatively. Stick to whole, natural ingredients whenever possible.
How Do I Test for Diabetes Insipidus in Dogs?
If your dog is showing any of the following symptoms, they may have diabetes insipidus:
- Increased thirst and urination
- Weight loss despite having a good appetite
- Lethargy or weakness
There are two types of diabetes insipidus in dogs: central and nephrogenic.
Central diabetes insipidus is caused by a problem with the pituitary gland, which regulates many hormones in the body including antidiuretic hormone (ADH).
ADH helps the kidneys to reabsorb water so that the body doesn’t become dehydrated. If there’s a problem with the pituitary gland, it doesn’t produce enough ADH, leading to increased urination and thirst as the body tries to compensate for the lack of water retention.
Nephrogenic diabetes insipidus is caused by a problem with the kidney’s response to ADH. Even if there’s plenty of ADH in the body, if the kidney isn’t responding properly, it can’t retain water leading to increased urination and thirst.
There are several ways to test for diabetes insipidus in dogs. The most common method is called an ACTH stimulation test. In this test, a vet will inject your dog with synthetic ACTH hormone and then measure their urine output over the next few hours. An increase in urine output indicates central diabetes insipidus while no change or only a small increase suggests nephrogenic diabetes insipidus.
Another way to test for diabetes insipidus is by measuring levels of vasopressin (the scientific name for ADH) in your dog’s blood or cerebrospinal fluid (CSF). Low levels of vasopressin confirm central DI while normal or high levels suggest nephrogenic DI.
A final way to diagnose DI is through genetic testing but this isn’t typically done unless other methods have been inconclusive or there’s suspicion that DI may be passed down through family members. If your dog is diagnosed with diabetes insipidus, treatment will depend on what’s causing it.
Central DI can often be managed with medication that replaces vasopressin while nephrogenic DI may require medication that helps reduce urinary tract infections or improves kidney function if possible. It’s important to work closely with your veterinarian to come up with a treatment plan that works best for your dog since every case is different.
Conclusion
There are two types of diabetes insipidus: central and nephrogenic. Central diabetes insipidus is caused by damage to the pituitary gland or hypothalamus, which leads to a decrease in the production of antidiuretic hormone (ADH). Nephrogenic diabetes insipidus is caused by damage to the kidney tubules, which limits their ability to respond to ADH.
As a result, dogs with either type of diabetes insipidus produce large amounts of urine and drink excessive amounts of water. Most cases of central diabetes insipidus are idiopathic, meaning the cause is unknown. However, it has been associated with trauma, tumors, infections, and other disorders of the pituitary gland or hypothalamus.
Nephrogenic diabetes insipidus can be congenital (present at birth) or acquired (develops later in life). It can also be caused by certain medications, such as lithium or demeclocycline. Dogs with either type of diabetes insipidus will urinate frequently and drink excessive amounts of water.
