You look at your dog’s x-ray with the vet and she says it looks like there is a calcium oxalate stone in the bladder. She recommends surgery to remove the stone and lab analysis to positively identify it. Sure enough, it turns out to be a calcium oxalate stone. Your heart sinks when the vet tells you that these stones have a high chance of recurrence even with the available diets for managing the problem. Your vet may not know that there is a diet with better success.
What Causes Calcium Oxalate Stones?
The exact cause of urinary calcium oxalate crystals and stones is unknown. But research has discovered certain patterns:
~Gender (73% of oxalate patients are male)
~Increased calcium in the blood caused by
-High calcium in the diet
-Excess vitamin C & D supplementation
* Overuse of diets to prevent struvite crystals and stones (excess urine acid)
The majority of dogs develop oxalate stones without having any medical problems.
What are the Signs of Oxalate Crystals or Stones?
Dogs with oxalate, or any stones for that matter, may have:
~Frequent urination of small amounts of urine
~Specks of blood in the urine or bloody urine
~Difficulty urinating, especially males
~Interrupted streams of urine or an inability to urinate ( this is an emergency in males)
~Painful with bulging tummies
What is the Treatment for Oxalate Stones?
Unlike some stones, calcium oxalate stones cannot be dissolved with diet. They must be surgically removed from the bladder and in rare cases from the kidneys. Dogs are then put on commercial veterinary diets to control crystals and stones in the bladder. Stones recur within months to years even with commercial veterinary diets.
Homemade Dog Food Recipes for Oxalates
Homemade diets are excellent for preventing calcium oxalate crystals and stones. A homemade diet with any meat or dairy product and white rice is an oxalate free diet. With proper calcium supplementation, these diets have proven effective in the management of calcium oxalate crystals.
The other advantage to homemade dog food is that it contains large amounts of water. The extra water in the diet dilutes any crystals and aids in preventing stone formation. Because these diets are extremely low in oxalates and promote dilute urine, concerns about urine acidity or pH become less important. Owners of dogs with a history of oxalates that are eating Hearthstone Homemade recipes and supplements report that veterinary urine tests from their dogs are consistently oxalate crystal free.
