Increased Thirst and Urine Production in Dogs


Polydipsia is a medical condition that indicates an increase in the thirst levels of a dog, while polyuria is a medical condition whereby the dog produces an unusually high volume of urine. Both these conditions should be evaluated by the vet in order to rule out grave diseases.

It is important to note that dogs affected by these diseases may not normally show any other changes or effects in their behavior. Therefore, it is extremely important to seek the advice of an expert. Factors like the size, breed, and medical history can help in diagnosis and treatment, so dog owners should be alert as to the activities of their dogs.

Is there a reason behind a dog acting unusually if it starts to drink from an open toilet or a dripping sink? Are there any reasons backed by vets to explain why a dog is having frequent and excessive accidents? All of these can be answered in the affirmative. The information below reveals how such behavior can be attributed to polyuria and polydipsia and provides basic information needed to deal with them.

What Causes Increased Thirst and Urine Production in Dogs?

There can be a series of underlying causes for increased thirst and urine production in dogs. These will be determined by a vet by examining each dog separately. While a major cause behind these two conditions revolves around congenital abnormalities, there are a lot of other causes worth your attention. A few of them have been listed below, but there are a lot of other causes not limited to this list:

A dog’s medical history may help determine the cause of increased thirst and urine production. This can be considered by the vet by evaluating the dog’s urinary and behavioral habits.

Furthermore, the vet can use it to determine the cause of the pain a dog might be feeling with increased thirst and urine production. The vet can keep this factor in mind while giving the dog a complete physical checkup in order to make sure the increased thirst and urine production are not a cause of grave concern.

Symptoms of Polyuria and Polydipsia

The conditions themselves act as sufficient symptoms. These are easily detectable if a close eye is kept on the dog. For example, dog owners may notice their dog frequently going out to relieve themselves, becoming unusually prone to having accidents or having new drinking habits.


Once the symptoms are apparent, you should take your dog to the vet for a professional diagnosis. The vet will diagnose your dog by testing and measuring the water it drinks and the urine excreted accordingly. The results will then be compared and contrasted to ensure they do not cross a level that signifies a grave illness. Usually, these tests include:

  • Urinalysis
  • X-rays to check the internal organ systems
  • Complete blood count
  • Water deprivation tests
  • Serum chemistry tests

Treatment for Polyuria and Polydipsia

Treatments differ according to each dog’s condition. Therefore, getting a proper medical diagnosis and following the vet’s instructions accurately is extremely important. Here are a few examples of what a vet might prescribe:

  • Limiting the amount of water your dog drinks
  • Antibiotics in case the polyuria and polydipsia are a result of an infection
  • Long-term treatments of hormone replacements for dogs with hormone imbalances
  • Improved diet and exercise
  • Chemotherapy in case the condition has been induced by cancer
  • Insulin management for dogs with diabetes

Home Care

This is the most convenient option available for dog owners. By home care, we mean keeping your dog under constant supervision so as to monitor any unusual activity, behavior, and diet intake. While there is no method to prevent these two medical conditions, constant vigilance and getting a vet involved in the early stages can help improve your dog’s health.

A Dog’s Recovery from Increased Urination and Thirst

Each recovery is different since it depends on the diagnosis. Some may take no time, while others may need a lot of time to recover. If these conditions have been triggered by a fatal disease, your dog may face obstacles in recovery. These diseases may even turn out to be fatal.


It is extremely important to monitor a dog’s increased thirst and urine production. Doing so indicates that the dog owner is responsible enough to ensure their pet’s life is not unnecessarily endangered. Dealing with it while its effects are still mild and adhering to the vet’s instructions are the best ways to deal with a dog’s increased thirst and urine production.
