Kidney Stones in Dogs
Can be every bit as painful as they are in people but there is one major difference

Kidney stones in dogs is known by another name; Nehprolithiasis. And yes, just like humans, your dog can and does get stones in their kidneys.

For anyone that has ever had one of these stones, the pain is absolutely horrible, and it is no different for your dog when it becomes severe.

The only difference is that your dog can not vocalize this pain.


Kidney stones in dogs are also referred to as Nehprolithiasis and are the presence of renal calculi that are located in the kidney pelvis.

They can cause extreme, bloody urination, and if they become severe, it will also cause your dog to vomit.

However, they can also cause infections in the kidney, and if these infections become severe enough, it can very easily cause the death of your dog.

For this reason, they should never be ignored and should be treated as quickly as possible.

One of the major functions of your dog’s urinary tract is to remove the body wastes in the form of fluid.

Some of these wastes are not always soluble in form, and as a result they may form crystals.

If these crystals remain in your dog’s urinary tract for any length of time, they interact and grow into stones.


Kidney stones in dogs can be just as painful in your pet as they are with humans, but there is one major difference, they may or may not show initial symptoms.

The actual signs of this potentially deadly condition will all depend on the exact location of the stones, as well as their size and the shape.

The number of stones that are present will also determine many of the actual symptoms.

Urinary tract infections that cause an increase in the frequency of urination as well as a lot of pain while urinating is usually the first symptom to surface.

The next symptom of kidney stones in dogs that you may see is small amounts of blood in the urine, and it will grow in intensity in some cases as the stones become larger.

Abdominal pains may be the next symptom, depending on the size of the stones and vomiting may also occur as the stones grow and intensify.

All of the symptoms may or may not occur, which makes this condition very difficult to spot by most owners.

However, even without these symptoms, if you suspect a urinary tract infection, treat it very seriously and have your dog checked as quickly as possible.

If the stones become severe enough and cause blockage, it can easily lead to kidney failure in your dog, or what is referred to as sepsis.

Sepsis is extremely dangerous as it is a situation where infection develops and then rapidly spreads into your dog’s entire bloodstream.

Once this occurs, your pet’s chances of surviving are not very good.


Kidney stones in dogs have several potential causes and the exact type of stone will have its own potential underlying cause.

There are five different types of kidney stones that can affect your dog, but by far and away the most common is called calcium oxalate stones.

They account for over 80 percent of all stones in dogs and are needle shaped crystals that have formed in the kidney.

The next most common type of kidney stones in dogs is called a calcium phosphate stone, and can be the result of a disease in your dog’s metabolic system such as thyroid condition.

Urinary tract infections can cause either form to develop as well as a genetic problem.

Kidney stones in dogs of any type are slightly more common in females than in males, and there are some breeds that are more at risk than other breeds.

Miniature schnauzers, Miniature poodles, Yorkshire terriers, Lhasa apso, and Cocker spaniels all seem to be more genetically inclined to developing stones than other breeds.

Dietary factors and well as supplements may also be the cause, as well as certain medications.


Treatment for kidney stones in dogs can vary dramatically, depending on the stone, its size, as well as the number.

If your dog is showing no clinical signs at all but it has been determined that your dog does have stones, they should not be left untreated.

Inactive stones may lay dormant for your dog’s entire life span, but they could also become active with without any warning.

The two most common forms of treatment are surgical or dietary.

Any type of surgery for stones is not without risk, and you should always seek a second opinion and then choose the most experienced veterinarian you can find.

If the stones have caused your dog’s kidney to start to fail, they will have to be surgically removed as quickly as possible.

This will involve cutting into your pets kidney and again should only be done by a very experienced professional.

If it is not life threatening, there is a procedure called ESWL, or Extracorporeal shock wave lithotripsy.

It is quite safe and very effective but can only be done in very specific locations where the medical equipment is utilized.

It basically crushes the stones with shock waves and then they are flushed out of your dog’s system. Antibiotic therapy may also be the treatment if the stones are not life threatening.

Fluid therapy is used in dogs that have become dehydrated or have severe forms of infections. Dietary treatments can also be very effective if the exact cause of stone has been established.

Excessive calcium in your dog’s diet can be the cause as well as phosphate, but limiting either of these in your dog’s diet can have huge ramifications on their overall health.

The calcium phosphorus balance in your dog is a very fine line and you should never attempt to adjust this balance without the specific guidance of your veterinarian.

There are several home remedies for kidney stones and dietary adjustments but they can cause a lot more harm than good.

It is worth repeating again, the calcium and phosphorus balance is critical for your dog’s overall health and should only be discussed with a professional.


Kidney stones in dogs can and does occur, and if it does happen, home care and follow up visits are critical to prevent re-occurrence.

However, there are a few things you can do to help prevent urinary tract infections which are the single largest cause.

If your dog is prone to these infections, moist food is much better than dry dog food for the obvious reason of more fluids.

Making sure your dog has plenty of water at all times as well a supplementing them with a urinary tract formula may prevent these stones from ever forming.
