“Struvite stones form in urine with a high pH (alkaline urine), diets should help to maintain a low pH (acidic urine). Diets with animal-based protein sources are most important in maintaining an acidic pH, while vegetarian or cereal-based diets are more likely to cause and alkaline urine”.
“With Calcium Oxalate stones, a high protein diet can cause stones by increasing calcium in the urine. It lowers urinary pH and can increase uric acid. High quantities of animal protein can contribute to stone formation by increasing urinary calcium and oxalic acid excreting and by decreasing urinary citric acid excretion”.
“Your should increase your dog’s water consumption to help dilute the urine. You can do this by adding water to your dog’s food, it should look like wet mush. Avoid table scraps when caring for an oxalate stone-forming dog”.
“Depending on the kind of stone, you either want more, or less protein, and lower in fat (3 -8%). Be sure to check with your veterinarian before changing your dog’s diet”.
