If your dog pees after drinking water, you are likely scratching your head, wondering about what may be going on. 

Can water go through your dog's body and urinary system so fast? This would seem to defeat the laws of physics! 

This doesn't seem to make any sense, especially considering that, after drinking, doesn't the urine need to filtered by the kidneys? So what may be going on? 

Discover several possible causes for dogs peeing after drinking. 

Help, My Puppy is Peeing After Drinking Water!

Peeing after drinking water is commonly seen in young puppies. Young puppies haven't attained yet sufficient bladder control to effectively "hold it," so they are big peeing machines when young.

Puppies being small, have small urinary tracts which predisposes them to frequent urination. Young puppies can pee as frequently as every 15 minutes to 30 minutes when active and playing. 

It may not be a coincidence that your puppy pees after drinking. Puppies tend to pee a whole lot and they are known for peeing after eating, drinking, playing hard and waking up from a nap.

In simple words, puppies lack the "I'm full!" signal that can prevent them from having accidents. A puppy will, therefore, need to eliminate as soon as she has a small amount of liquid in her bladder.

Most of the time, this excess peeing is not due to an underlying medical problem, and therefore resolves with age, explains veterinarian Dr. Burch.

Young pups lack sufficient bladder control, and on top of that, they produce a lot of waste materials as they are growing. 

Signs of Trouble in Puppies 

If your puppy is peeing *more frequently* than before or if you notice signs of trouble such as frequent attempts to urinate with little or no production,  pain while urinating, accidents in the house, excessive licking of private areas, blood in the urine, or a malodorous smell to the urine, please see your vet. 

Although a urinary tract infection in a young puppy isn't very common, they do occasionally pop up. Female pups are more predisposed than males due to their anatomy. 

 On top of bladder infections, puppies who pee a whole lot may be suffering from other conditions such as bladder stones (there have been cases of them being found in predisposed pups such as miniature schnauzers and Dalmatians as young as 3 months old!) or congenital disorders (inherited malformations of the urinary tract).

Puppies may be also suffering from certain endocrine disorders (like diabetes mellitus) which results in them drinking more water and therefore having to urinate more often.

If your puppy is therefore urinating more frequently than before or exhibiting concerning signs, please have him or her see the vet sooner than later. 

Help, My Dog is Peeing After Drinking Water!

If your dog is peeing after drinking water and he is not a young puppy, you may be wondering what is going on.

Adult dogs should be capable of "holding it," but several medical and non-medical issues can be causing the signs you are seeing.

 Following are several possible causes for an adult dog peeing after drinking water.

Urinary Tract Infection

A urinary tract infection is one of the most common causes for dogs to pee often. Inflamed bladder tissue makes a dog urinate more often and in smaller volumes, which is ultimately uncomfortable for the dog.

In addition, your dog may pee in unusual locations, develop blood in the urine, and lick her private area more often.

If you notice your dog peeing after drinking, visit your vet. Bring along a fresh urine sample if you can. Your dog may need a course of antibiotics.

Bladder Stones 

Bladder stones are made of minerals that clump together in the dog's urinary tract and obstruct urine flow. 

Signs include frequent urination, blood in the urine, and recurring urinary tract infections.

Kidney Problems 

If your dog is experiencing increased thirst and is therefore drinking more than normal, he may be suffering from polydipsia, an abnormally high sense of thirst which is a common symptom of kidney problems.


Diabetes in dogs is similar to diabetes in humans and is a chronic condition where the pancreas fails to produce enough insulin. This leads to too high levels of sugar in the blood.

 When your dog has high blood glucose levels, he will drink more water to flush out the excess glucose. This results in lots of peeing.

Different Types of Pain in Dogs

There are different types of pain in dogs and differentiating one from another can help you better understand your companion.

Congenital Malformations 

These are hereditary defects that are passed down from a generation to another.

One of them is ectopic ureter  This condition is not uncommon in female dogs, and can cause a significant amount of urine leakage. 

The ureters carry urine from the kidneys to the bladder, but when they become ectopic, they bypass the bladder and drain into another part of the body. 

Most ectopic ureters are discovered when pups are 3- to 6-month-old dogs. Females are 8 times more likely to have this than males.

An ectopic ureter can be surgically corrected. The surgical procedure performed to correct an ectopic ureter will correct the incontinence. 

Urachal remnants is another congenital issue. Prior to birth, the urachus consists of a tube that connects the pup's bladder to the umbilical cord so that wastes can be expelled. 

After birth, this tube normally closes turning into a cord of fibrous tissue extending from the bladder to the navel. 

In some dogs, the urachus fails to close properly after birth. Depending on what part remains open, it can be called a patent urachus or an umbilical urachal sinus.

 Further problems are urachal diverticula, which consist of small sac-like structures attached to the urachus and urachal cysts. 

Symptoms consist of inability to control urination, urinary tract infection and urine scalding of the skin near the navel.

There is also an acquired form resulting from underlying conditions causing excessive pressure on the bladder.

Psychogenic Polydipsia

Psychogenic polydipsia takes place when the dog drinks too much water. This floods the kidneys with so much water, the kidneys can't keep up and are unable to concentrate urine. This causes dogs to be urinating constantly. 

Dogs Obsessed with Drinking Water

You should not restrict your dog's access to water unless recommended by a vet.

Should I Restrict My Dog's Water?

It may be tempting to try to tackle the issue of a dog peeing after drinking by removing water, but this practice can turn out being harmful.

Just imagine depriving water to a dog who really needs the water so to flush his body from excessive waste products that could precipitate a cascading chain of unhealthy events. 

Dog owners should therefore never restrict water until knowing what the lab work says, and then the vet making this specific recommendation.

What Happens After Dogs Drink?

After your dog laps up a bowl of water, it is processed through an abbreviated digestive process. 

In a nutshell, not all of your dog's digestive organs need to be  involved. It's a simplified process and rather quick. 

Indeed, water passes through your dog's body quicker than food. 

Once the water goes down the dog's throat, it enters the dog's stomach and is then processed through the dog's small intestine where it's for a great part absorbed into the dog's bloodstream. The large intestine also absorbs some level of water. 

Any excess fluid is filtered by the kidneys and then the rest is sent to the bladder from which it is then excreted. 

Did you know? Since water passes through your dog's body so quickly, it’s important that he stays hydrated so to maintain optimal fluid levels. 

How Often Do Dogs Pee?

You may find it interesting to learn that urine production is constant and depends on a variety of factors such as the condition or hydration status of the dog.

If you're looking for a ballpark figure, therefore consider that there are many variable such as the dog's overall condition, his hydration status and other technical factors such as your dog blood urea nitrogen, creatinine levels and urine specific gravity, explains veterinarian Dr. Michelle.

Dehydrated dogs will urinate less frequently than well-hydrated dogs and dogs on certain medications (such as steroids) will urinate much more as they drink more.

In general though, expect puppies to pee quite frequently (even as frequently as every 15-20 minutes to half hour when active and playing).

Adult dogs with a normal bladder capacity instead can hold urine for several hours, even up to 6 to 8 hours.
