Noticed your dog drinking more water lately? While occasional increases in thirst can be due to factors like activity or weather, consistent excessive drinking, known as polydipsia, can signal underlying medical issues. When paired with increased urination or polyuria, it's especially concerning.
Typically, excessive thirst is characterized by a dog consuming more than 100 mL of water per kilogram of its weight daily. A short-term spike in water intake over a few days, perhaps due to rigorous exercise or a heatwave, usually isn't a cause for alarm. However, if you find your dog's thirst consistently elevated, monitoring and assessing the situation is crucial.
Let's explore the potential causes and solutions for your dog's increased thirst!
1. Diabetes
Both forms of diabetes, mellitus and insipidus, can lead to dogs drinking more water than usual. While diabetes mellitus is typically managed with insulin shots, dietary adjustments, and weight management, the treatment for diabetes insipidus often involves desmopressin acetate.

2. Cushing's Disease
Dogs with Cushing's Disease often experience a notable increase in thirst. In such cases, vets might suggest medicines like Lysodren to regulate the cortisol levels in the dog's system.
3. Kidney Disease & UTIs
Issues like urinary tract infections or varying degrees of kidney disease can disrupt a dog's ability to process and retain water efficiently. When faced with kidney-related challenges, a vet might opt to provide the dog with subcutaneous or intravenous fluids to combat dehydration.
4. Liver Disease
A dog showing signs of increased thirst and frequent urination might be grappling with liver disease.
5. Medications
Anti-inflammatory drugs like prednisone, diuretics, phenobarbital, and seizure and heart medications can all cause excessive thirst and urination in dogs.
6. Pyometra
Uterine infection or pyometra, a condition that affects unspayed female dogs may also cause a dog's increased thirst.
7. Toxicity
Human foods like onions, avocados, grapes, raisins, and chocolate can harm dogs. A sudden increase in thirst in dogs may indicate toxicity.
8. Other Conditions
Sometimes, the cause behind a dog's increased thirst can be as straightforward as a fever or a bout of diarrhea. However, these symptoms can also hint at more complex medical conditions, like hypercalcemia. A vet might prescribe specific medications or recommend intravenous fluid therapy in such instances.
What Should I Do If My Dog Has Increased Thirst?
If you've observed your dog drinking excessively for several consecutive days, it's time to consider a visit to the veterinarian. This behavior might be a sign of an underlying medical issue. It's particularly concerning if, along with increased thirst, you notice signs of dehydration such as:
- Fatigue
- Dry gums
- Thickened saliva
- Sunken eyes
- Loss of skin elasticity
During your visit, the veterinarian will conduct a thorough physical examination and order comprehensive lab tests. The results from these tests will help in diagnosing the issue. For example, elevated blood sugar levels can be a sign of diabetes mellitus, while a spike in white blood cells might suggest an infection.
If these initial tests don't pinpoint the problem, your veterinarian may suggest additional diagnostics. This could involve a water deprivation test or specific imaging to get a clearer picture of what's happening inside your dog's body.
Conclusion
Your dog's health is paramount. While many factors can influence thirst, consistent changes, especially with other symptoms, warrant professional insight. Don't leave your pet's health to chance; ensure your furry friend's well-being with a timely veterinarian visit.
