Treatment recommendations

During COVID19 some canned foods may not be available or on backorder.  If a dry food is substituted, be sure to add water to the food.  Additional water intake has a beneficial effect in minimizing recurrence of stones.  See Does Water Type Matter.

Each of our recommendations contains characteristics to look for in prevention or treatment. Foods listed are those we are familiar with using. Other diets may be appropriate.  If the foods suggested do not meet your needs, the flowsheet for your pet’s urolith mineral type lists the urine parameters (specific gravity and pH) to strive to achieve.

Recommendations are now available in multiple languages on our iphone and android app. Learn more

Human Foods

Human Foods

Literature from human studies can provide some information on foods high (or low) in minerals (eg. calcium and oxalate).  This information may assist some owners who select human food as treats.

In most cases, if treats comprise less than 5-10% of the diet, they most likely will not affect prevention strategies to minimize urolith formation.
