Protect Your Dog from Kidney Stones with the Kidney Stone Prevention Diet (Calcium Oxalate)

Dog with kidney disease

Help Your Dog Feel Better with the Kidney Stone Prevention Diet

Our kidney stone prevention diet works for calcium oxalate bladder and kidney stones.

And, it helps with urinary crystals, too.

Calcium Oxalate stones are the most common form of bladder and kidney stones found in dogs. 

If your dog has suffered from oxalate kidney stones in the past, then feeding your dog a diet low in oxalates decreases the risk of future recurrence.

This diet intends to eliminate as much oxalate from your dog’s diet as possible.

By following our dietary recommendations, you will decrease the risk of recurrence. The recipe below is Dr. Smith’s modification of his PET | TAO formula, eliminating high-oxalate food ingredients and focusing on low-oxalate food ingredients.

The plan is a quick, easy way to make the necessary dietary changes to keep your dog’s body from forming oxalate stones.

The Bladder and Kidney Stone Prevention Diet Plan


  • Feed 1 cup per 10 pounds of body weight. Vary according to your dog’s individual needs.
  • Feed your dog a canine multivitamin in addition to the home-cooked diet.
  • Add 350 mg of Calcium Citrate for every 8 ounces of food you make. Combined with your dog’s food, it will bind to the oxalic acid in the digestive tract. The bound oxalate cannot be absorbed into the bloodstream and is then excreted through the feces.
  • Protein/Fat/Carb Ratios: Get as close to possible to:
    • 60% – 80% Protein – mostly from meat
    • 20% – 40% Carbohydrates – from grains, vegetables, and fruit
    • A minimum of 2% fat
  • Food Preparation: Boiling significantly reduces the oxalate content of the vegetables. Soaking overnight, discarding the water, then boiling and again discarding the water dramatically reduces the oxalate content of grains.

Kidney Stone Prevention Diet Plan Recommended Foods

The best way to prevent oxalate kidney stones in dogs is to feed them low-oxalate foods. The following list will help you choose the best foods for your pet.

Low Oxalate Foods

The foods on the following list are all low in oxalate can be fed as often as you like.
