Each dog is unique, and this individuality extends to their bathroom habits too! But what do you do if your dog suddenly needs to urinate more than usual, urinating eight or even ten times a day instead of their usual three to five?

Frequent urination in dogs can be caused by multiple factors including age, excessive drinking of water, behavioral issues, and underlying medical conditions.

As a pet parent, it's essential for you to understand the underlying reasons for excessive urination in dogs, so you can spot the signs and get prompt diagnosis and treatment for your pet.

Here are the most common reasons for excessive urination in dogs:

1. Age

Puppies urinate more frequently than adult dogs because they drink water more often, and their bladders are smaller. Generally, puppies can hold urine for the hours equivalent to their age in months.

Adult dogs tend to urinate every four to eight hours depending on their breed and size, while senior dogs urinate more frequently.

2. Excessive Drinking of Water

Your dog may drink lots of water when the weather is hot or after strenuous exercise. However, prolonged high water intake could signify a medical issue, so you should consult your veterinarian for a proper analysis of the situation.

How Much Water Should My Dog Drink in a Day?

Based on your pet’s weight and energy level, your dog should be drinking approximately ounces of water per day

On hot days, expect your dog to need more water. Adult dogs will generally drink when thirsty, so make sure to provide lots of cool, fresh water for them. Puppies and senior dogs may need to be reminded to keep up with their water intake, so if you do not observe them drinking regularly, make sure to lead them to their water bowl and encourage them to drink.

The above calculator is meant to serve as a general guide for your pet. Every dog has their own unique needs, and therefore, we recommend that you speak to your veterinarian if you have concerns about your pet’s nutrition, including how much your dog should be drinking each day.

3. Electrolyte Imbalances

Electrolyte imbalances, especially those involving sodium or salt, can lead to excessive thirst and increased urination in dogs. These imbalances may arise from high-sodium meals, dehydration, toxins, or other medical issues. It's essential to avoid giving pets high-sodium foods and ensure they always have fresh water available. 

If you're concerned about persistent symptoms or your pet's water intake, it's best to consult a veterinarian. They can offer advice, conduct necessary tests, and recommend appropriate treatments.

4. Behavioral Issues

If you see your dog urinating a lot during walks or when visiting new locations, it could be marking territories.

Unspayed female dogs will urinate frequently when coming into heat. Other behavioral reasons for increased urination include anxiety or significant shifts in their living environment or routines. 

Addressing such behavioral issues can sometimes require a deeper understanding of canine behavior.

Concerned About Your Pet's Unusual Behavior?

Get peace of mind with expert counseling. Identify the reasons behind common behavior challenges and nurture a fulfilling bond with your beloved pet.

5. Urinary Tract Infection (UTI)

Urinary tract infections are fairly common in dogs, especially in females. They are often referred to as bladder infections and occur when bacteria from the external environment, such as E. coli, enter the bladder.

The most common symptoms of urinary tract infections include frequent, small amounts of urination, and straining to urinate. If you notice your dog suddenly urinating frequently, a UTI could be the culprit.

6. Medication Side Effects

Certain medications, such as corticosteroids, diuretics, and anticonvulsants, may cause increased thirst and urination in dogs. It is essential to inform your veterinarian if your dog is urinating a lot when taking such drugs.

Your veterinarian may adjust the doses or make further recommendations to alleviate the problem.  

7. Spaying and Neutering Effects

Hormonal-responsive incontinence, also called urethral sphincter mechanism incompetence (USMI), occurs due to a decrease in the hormone estrogen, affecting bladder storage capacity and sensitivity of the sphincter muscles. It commonly affects spayed female dogs, and can lead to urinary incontinence.

8. Bladder Stones

Bladder stones are rock-like mineral formations in the urinary bladder. They are distinct from bladder infections and are characterized by bloody urine (hematuria) and difficulty urinating (dysuria). Your dog will experience frequent urination and pass small amounts every time.

Diagnosis of bladder stones is done via X-rays, ultrasound examination, or radiographic contrast study. There are three treatment options depending on the makeup of the stone: surgical removal, urohydropropulsion, and dietary dissolution.

9. Cushing's Disease

Also known as hyperadrenocorticism or Cushing's disease, the condition results from the overproduction of the hormone cortisol. Excess cortisol weakens your dog's immune system, predisposing them to other diseases and infections.

Cushing's disease is characterized by increased thirst, increased urination, and elevated appetite among other symptoms.

Diagnosis requires blood tests and ultrasounds, and treatment involves management with medications.

10. Canine Diabetes

Diabetes mellitus is the most common type of diabetes in dogs. It is the underproduction of insulin or the inability of your dog's body to respond to insulin. Canine diabetes causes excessive thirst and increased urination.

Treatment and management involve insulin therapy, periodic blood testing, and monitoring.

11. Kidney or Liver Disease

Kidney disease hampers the kidneys' ability to efficiently filter waste products from the blood. This results in excessive urination.

Excessive urination and thirst can also result from liver disease. Diagnosis involves various blood tests, X-rays, ultrasonography, and aspiration or biopsy procedures.

Early treatment is critical if your dog is suffering from kidney failure or liver disease.

What Should I Do if My Dog Is Peeing Excessively?

Frequent urination in dogs can be an indicator of underlying medical conditions. Consult your veterinarian immediately if your dog is urinating a lot and has the following signs:

  • Blood in the urine
  • Straining to urinate or producing no urine
  • Urinary accidents
  • Discolored urine
  • Vomiting
  • Loss of appetite
