Considerations Urethral obstruction Protein and mineral levels may be to low for growing animals or gestating and lactating bitches. Breed, age, pH have little effect on formation. Hypercalciuria Excessive intestinal absorption of Ca Impaired renal concentration of Ca Excessive skeletal mobilization of Ca Hyperoxaluria Ascorbic acid and amino acid metabolism oxalic acid formation. Dietary Management Prophylactic prevention Depends on preventing saturated Ca and oxalate concentrations in the urine. Uncoupling calcium from sodium excretion into the urine with a Thiazide diuretic .
