If your dog only pees once a day, it can be worrying since most dogs urinate multiple times in 24 hours.
Sometimes this is normal depending on routine and water intake, but it can also be a red flag for underlying health issues.
We outline the common reasons why a dog only pees once a day, what you can do at home, and when to seek veterinary help.
Dog Only Pees Once a Day — Why It Happens
A dog only peeing once a day can happen due to limited water intake, bladder control, or underlying health issues. Some dogs naturally hold their urine for long periods, especially if they are well-trained and not provided frequent bathroom breaks. Others may urinate less due to dehydration, kidney problems, or urinary tract issues.
Occasional once-a-day peeing may be harmless, but when paired with other concerning signs, it needs closer attention.
Dog Only Pees Once a Day: Common Causes
Low Water Intake
One of the most common reasons a dog only pees once a day is dehydration. Dogs that don’t drink enough water won’t produce enough urine, leading to infrequent bathroom trips.
This can be caused by limited access to fresh water, hot weather without adequate hydration, or a preference for wet food over drinking from a bowl.

Strong Bladder Control or Limited Bathroom Breaks
Some dogs are capable of holding their urine for long stretches, especially those who are house-trained and accustomed to a strict routine.
If a dog isn’t offered frequent outdoor opportunities, they may only pee once daily.
While this shows bladder control, consistently restricting bathroom access can put stress on the urinary tract and bladder.
Urinary Tract Infection (UTI)
UTIs can sometimes cause dogs to pee less, though they are more often associated with frequent urination.
In certain cases, infection or inflammation makes urination painful, so the dog holds it longer.
You may notice straining, discomfort, or blood in the urine. Left untreated, UTIs can spread to the kidneys and cause more severe issues.
Kidney Problems
The kidneys regulate fluid balance and waste removal. If they aren’t functioning properly, urine output may decrease significantly.
Dogs with kidney issues may also show signs like lethargy, vomiting, or changes in appetite.
Only peeing once a day alongside these symptoms should be taken seriously and evaluated by a vet.
Bladder Stones or Obstructions
Physical blockages such as bladder stones can limit a dog’s ability to urinate. In severe cases, a complete blockage may occur, which is a life-threatening emergency.
If your dog strains, dribbles small amounts of urine, or seems unable to go despite trying, seek veterinary help immediately.
Hormonal or Metabolic Conditions
Diseases such as diabetes or Cushing’s disease can change a dog’s urination patterns. While they often lead to more frequent urination, they may also cause irregular or reduced urination in certain stages.
If your dog only pees once a day but also shows excessive thirst, weight changes, or unusual behavior, it may be linked to a metabolic condition.
What to Do If Your Dog Only Pees Once a Day
If your dog pees once a day but otherwise seems healthy, eats and drinks normally, and shows no signs of pain, it may not be cause for concern. Still, it’s important to monitor their water intake and bathroom habits closely.
Encourage hydration by offering fresh water throughout the day. Some dogs prefer running water, so pet fountains can help. Adding water or broth to meals can also increase fluid intake. Make sure your dog gets regular opportunities to go outside and relieve themselves comfortably.
If you notice your dog straining, producing very dark urine, or appearing uncomfortable, consider adjusting their routine and watch for improvement. Sometimes simply allowing more bathroom breaks resolves the issue.
However, never ignore sudden changes. If your dog previously urinated multiple times but now only goes once daily, this shift may be a sign of an emerging medical issue.
When to Call or Visit Your Vet
If your dog only pees once a day and also shows signs of dehydration, lethargy, or appetite loss, it’s time to contact your vet. Sudden changes in urination should not be dismissed, especially if paired with unusual behavior.
Seek emergency care if your dog strains without producing urine, dribbles small amounts, or seems unable to pee at all. These can indicate a blockage, which is life-threatening if untreated.
Other warning signs include blood in the urine, foul odor, or visible discomfort when peeing. These suggest infection, stones, or kidney disease, all of which need veterinary diagnosis and treatment.

Key Takeaway
A dog only peeing once a day may be normal for some pets, especially those with strong bladder control or limited outdoor breaks. However, it can also signal dehydration, kidney problems, or urinary tract issues.
Monitoring your dog’s urination, hydration, and behavior is the best way to protect their health. When in doubt, consult your veterinarian to ensure your dog’s urinary system is functioning properly.
