Frequent Urination in Dogs

Frequent urination in dogs can be a concerning sight, and of course for many of us there will be the panic that this might be being caused by something sinister such as bladder or prostate cancers (at the same time it’s just annoying having to keep opening the door to the garden… ).

While this is of course sometimes the case, you needn’t alarm yourself right away and there are many other explanations for why your dog might be frequently urinating which we shall address here. Following are some reasons your dog might be regularly urinating.

Urinary Infections

The single most common cause of frequent urination in dogs is canine urinary tract infections such as canine cystitis. Here your dog’s bladder will become inflamed from an infection and this will cause them to need to empty their bladder more often as a result. This is most common in female dogs due to their shorter and broader urethra, meaning it’s easier for bacteria to get in. Young dogs are also susceptible to this problem.

Bladder Stones

If your dog has a very high mineral diet then they may develop bladder stones which are pea/gravel sized stones that form in the bladder and result in urinary problems. These may need to be removed from your dog’s bladder surgically.


Diabetes can affect dogs just as it can affect people. Here your dog will have too much sugar in their blood stream and they will then urinate more regularly in a bid to rid their body of this sugar. They will likely also exhibit symptoms such as lethargy and this can occur as a result of eating too many sugary foods.

Hormone Imbalance

Again common in female dogs is hormone imbalance which affects the kidney function. This can be quiet a serious issue causing your dog to become dehydrated (you might notice them drinking a lot). This is a more common in older dogs too.

Crushing’s Disease

The symptoms of Crushing’s disease are often mistaken for ageing, and they involve things such as thinning hair and drinking more – which results in more frequent urination. It is more common in older dogs too though which is part of what makes this confusing to diagnose.


If there is blood in your dog’s urine then they are more likely to be experiencing cancer (though not necessarily). This may be treatable just as cancer can be treated in humans, so don’t give up hope just yet.

In any case, if you find your dog is urinating more often than it previously did, then you should take it to a vet who will be able to diagnose the precise cause for the problem and recommend treatment.


  1. Correct medical name is Cushings disease. Very little effort or information went into this article.

  2. It was clear and very helpful, thank you.
