What are bladder stones and what are the symptoms?

Bladder stones, as their name suggests, are stones that form in the bladder. They can vary in size. There are sand grain-sized, and gravel-sized too. Some dogs have bladder stones of various sizes. In terms of their material, these stones are made up of various minerals. They are most common in the bladder, but can also form in the gall-bladder and kidneys.

If your dog has bladder stones, you may notice the following symptoms:

  • Urinary accidents
  • Straining to urinate
  • Pain during urination
  • Frequent urinating
  • Discolored urine
  • Frequent but small amounts of urine

How do you diagnose bladder stones in your dog?

In the early stages, many dogs do not show symptoms. Regular vet checks can help detect the problem in a timely manner.

For successful treatment, it is necessary to determine which bladder stone we are dealing with. Of course, this will go easily for your vet. There are four types of bladder stones:

  • Calcium oxalate: When dogs take in too much calcium, some of the excesses are not excreted. Instead, it is converted to oxalate. Stones are formed later from this oxalate. The thing is interesting because when there is a deficiency of calcium, the body produces oxalate too. This can also lead to bladder stones later on. Otherwise, calcium oxalate forms in acidic urine. The formation of oxalate crystals can be reduced by reducing the concentration of ions and metabolites in the urine.
  • Struvite: Struvite stones are formed in alkaline urine when there is a lot of excess magnesium and phosphate.
  • Urate: Urate stones are formed in acidic urine. The reason is usually purine, which is found in virtually every meat.
  • Cystine: Cystine stones are usually formed due to excess protein in acidic urine.

As you read this article, I think you also know that bladder stones can usually be treated with proper dog food. Once your veterinarian has determined the type of bladder stone, dietary steps can come.

What to look for in the best dog food for bladder stones?

Now let’s look at what ingredients to look out for:

  • Moisture: A lot of fluids have a very good effect on bladder stones. For this reason, the moisture level is the first factor you need to consider when choosing. Prefer wet dog food over dry kibble. If for some reason your dog doesn’t like wet food, mix it with dry food. Experiment with proportions. However, it is critical to provide enough fresh water for your dog. Also, ask your veterinarian for help.
  • Minerals: Look at the ingredients and the mineral content of the food. Materials that cause stones should be avoided. And it is good to know what kind of bladder stone your dog has. That way you will know what are the minerals that are beneficial to him. For example, magnesium and phosphate should be avoided in alkaline urine. However, they have a particularly beneficial effect on stones formed in acidic urine. Caution should be exercised with calcium. As I mentioned, both too much and too little calcium causes oxalate formation. Of course, your vet will be able to help you with this as well.
  • Other minerals: Sodium chloride basically has a good effect on bladder stones as it dilutes the urine. However, you have to pay close attention to this. Dogs are much more sensitive to salt than humans. Your dog will be easily dehydrated from a lot of salt. Potassium citrate helps dissolve calcium oxalate. So if you are dealing with this type of stone, you may want to look for this mineral in dog food.
  • Vitamins: Avoid vitamins C and D. These vitamins are able to control oxalate formation and calcium balance. According to research, it all usually goes in the wrong direction.
  • Other ingredients: There are some ingredients that you should avoid unless your veterinarian recommends them. These include brewer’s yeast, cranberry products, cider vinegar, collagen, and spinach.
  • Protein: Cystine stones are formed due to excess protein. Therefore, you should reduce the amount of protein consumed in the diet of dogs with cystine stones. Proteins (more specifically meat) also cause urate stones. There are cases where proteins may prevent stones from dissolving. So usually, proteins need to be moderated.
  • Fiber: The fibers are very healthy, but you need to pay attention to them if you have a dog with bladder stones. This is because fibers absorb moisture, which would help dogs with this condition anyway. This does not mean that you have to completely avoid fibers. They are very healthy and essential for proper digestion. But strive for moderated fiber content.

Are there breeds that are more prone to bladder stones?

All dogs have a chance of developing bladder stones. It is not possible to know exactly why this condition develops in some dogs and not in others. Causes may include genetics, changes in urine pH, dietary changes, or various infections. However, researchers have found that bladder stones are more common in some dog breeds. 

These breeds are:

  • Beagles
  • Basset Hounds
  • Cocker Spaniels
  • Bulldogs
  • Dachshunds
  • Miniature Schnauzers
  • Dalmatians
  • Pekingese
  • Welsh Corgis
  • Pugs

How to treat bladder stones in dogs?

If you notice any of the symptoms already mentioned in your dog, the first and most important thing is to consult a veterinarian. Bladder stones are not fatal but are extremely unpleasant for canines. That is why I suggest that it is better to ask for help as soon as possible.

Your veterinarian will start by reviewing your dog’s medical history and a physical examination. Feeling the abdomen usually lets you know if there are any stones. 

After all, your veterinarian may suggest a number of other complicated tests. Examples are the electrolyte tests, the thyroid body, or the X-rays of the urinary tract. If he confirms the diagnosis of bladder stones, you can start thinking about treatment together.

Here are some options for bladder stones treatment:

  • Surgery: Surgical removal is one of the most common and quickest treatments. During the surgery, the vet will cut and open the bladder and remove the stones. This method is not applicable to dogs with certain medical conditions. Examples of such conditions are bleeding disorders or sensitivity to anesthesia.
  • Removal without surgery: Using a technique called Uro hydro propulsion, the veterinarian inserts a catheter into the bladder. After that, he simply flushes out the stones. Of course, this is only possible with small bladder stones.
  • Diet: As I wrote earlier, dietary changes can avoid surgeries in many cases. However, be sure to perform a bladder stone analysis. Because only then can you put together the right diet. Improvement often takes weeks or months.
  • Ultrasonic dissolution: High-frequency ultrasound waves break up the bladder stones. After this, the smaller pieces of stone will be able to leave the bladder.

Most veterinarians recommend dietary dissolution. On the one hand, this is the most natural method, and on the other hand, it can prevent reforming. In all cases, talk to your veterinarian about dietary changes.

What Relative Super Saturation (RSS) in dogs’ diet?

This is a chemical concept that can be used to predict the size of crystals as they precipitate out of the solution. The slower the precipitation, the larger the crystals will be. Experts have found that by changing the composition of the diet properly, precipitation can be slowed down or even prevented. Struvite crystals, for example, can be easily dissolved at low RSS values. And how to achieve a low RSS value? We need to dilute the urine or reduce the concentration of minerals in the urine. In addition, we need to change the acidity or alkalinity of the urine.
