Increased Thirst in Dogs Veterinarian

We all know how exercise, running errands or a hot summer’s day can help strike up a thirst. Your dog responds the same way when they run around the yard or play outside. You may feel a bit concerned if you notice that your dog starts to drink excessively, or drink more than he or she normally does. As a dog owner, you should be aware of when your pup finishes an entire water bowl in one sitting, or drinks water every time it is offered to him or her. Polydipsia (drinking excessive amounts of water) may be a symptom of an underlying medical problem. Behavioral displays of frequent urination, or starting to drink from the toilet are red flags that your pup can be suffering from a potential disease.

Before you begin to worry, there are some causes that could explain your dog’s increase in thirst that do not stem from an underlying medical condition or disease. As a way to rule out more life-threatening conditions, you should first ask yourself a few questions.

  • Have I increased the amount of activity I give my dog? Exercising your pup more frequently or letting him outdoors more often than before could be an explanation of why your pup has become thirstier.
  • Has there been an increase in temperature? Weather is an external factor that plays a part in the desire for water consumption, especially on the hot, humid days.
  • Does your dog take any new medications? As we know there are many side effects that can occur when taking a medication, dry mouth and thirst can be some of them. Steroids, in particular, are known to cause increased thirst and accompanying urination.
  • How old is your dog? Active and playful puppies may drink a little more water than adults.

If you find that none of the above pertain to your pet, there may be an underlying medical condition or disease. It is best that you have your dog seen by a Veterinarian as soon as possible, and for him or her to receive a thorough physical examination and diagnostics to look for an underlying cause.

Medical Causes

There are several medical conditions that associate with polydipsia in dogs. To name a few:

Diabetes
Diabetes is the most common disease in dogs that causes an increase in water intake. This type of thirst is a result of high blood glucose levels and your dog’s body’s attempt to decrease this concentration. In rare cases, central diabetes causes a depletion of ADH hormone, resulting in profound drinking and urination.

Kidney Failure
When your dog is suffering from kidney failure, his or her kidneys are no longer able to remove waste from the body in the concentration of urine. This will then cause a response of increased water drinking by your pet.

Liver Failure
In the case of liver failure, your dog’s body is no longer able to filter toxins from the bloodstream. Increase in water intake is a measure to prevent these toxins from accumulating in the body.

Cushing’s Disease
This disease is caused by a benign or cancerous growth on the pituitary or adrenal glands of your dog. The overproduction of steroids results in increased urination.

Although an increased level of your dog’s thirst may seem like a harmless new behavioral trait, it often correlates to something more serious. Bringing your dog into our Veterinary Hospital can allow you to receive an accurate diagnosis and treatment plan for your pup.
