Calcium oxalate bladder stone in dogs

 Dogs are just like people and, they can develop stones in bladder and kidney.

  The rock-like bladder stone is more common than kidney stone in dogs,and there are two forms. One is called “Calcium oxalate bladder stone” and the other is called “struvite stone”.

When dogs have stones, it is not always the case where the vet has to remove the stones.Hoewever, if you did not know which types of stones your dog got, your vet would not know what type of approach he/she should take to get your dogs feel better, how to prevent it to happen again..

Therefore, often times, surgically removed stones are sent to lab to analyze it.

In this entry, I would like to write about calcium Oxalate bladder stone in dogs.

How these oxalate stones are formed?

According to VCAhospital website, normal dog’s urine is slightly acidic and contains waste products from metabolism  including dissolved mineral salt. These mineral salts will be remain dissolved in the urine.

 The current research shows that urine high in calcium,citrate, or oxalate is acidic and predisposed them to develop calcium oxalate crystals and stones.

Also, diet that causes high urine acidity (urine PH <6.5) may predispose the dog to form the calcium oxalate bladder stone.

Interesting thing they write is that, the dogs on antibiotic too much,too long may reduce the number of intestinal bacteria Oxalobacter formigenes,which  has sole nutrient of oxalate.

In dogs with low number of intestinal bacteria “Oxalobacter formigenes”, the excess oxalate will be secreted in urine and increase the high possibility of calcium oxalate crystals stones can form if the urine is highly concentrated or acidic.

  Another point to note is that the dog with Cushing’s disease produce more cortisol (cortisone) and predispose them to develop the calcium oxalate stone.

According toveterinarypartner website ,cortisone increases calcium excretion in urine,and extra calcium in urine promote the formation of the stone.

What are the symptoms for calcium oxalate stone?

Typically, you may see blood in urine, straining to urinate, frequent urination.

What can you do to prevent them to develop calcium oxalate stone in the future?

With this type of bladder stone, you can feed them customized meal to control the likelihood of developing another calcium oxalate stone.

It is very helpful if you know which food has most/least calcium oxalate in it to provide the diet that makes their urine less acidic.

Often times, grain, vegetables are high in oxalate, and since many kibble is made from grain and vegetables as the base, switching their diet to homemade diet or raw diet might help.

If you were not ready to switch their diet to homemade diet or raw diet, you can switch them to canned food to start. The canned food has more protein than dry kibble and it got more moisture in the food compared to the dry kibble.
