If your dog is suffering from severe hypophosphatemia, your veterinarian will need to hospitalize the dog for immediate treatment. If the condition is caused by insulin therapy or intravenous nutrients and vitamins, these treatments will be suspended until supplemental phosphate has been administered for a few hours. If a condition of anemia is present, fresh whole blood transfusions may be required. Conversely, if your dog is only suffering a moderate case of hypophosphatemia, it may be treated on an outpatient basis as long as its condition is stable.
Your veterinarian will need to measure your dog's phosphorus levels every 6–12 hours until the concentration of phosphorous remains stable within the normal range. If hyperphosphatemia recurs, all supplementation will be stopped and your dog will be provided with intravenous fluid until the phosphorus levels return to normal. Follow-up care will include monitoring your cat's condition for acute (sudden and severe) renal failure, a condition that some hyperphosphatemic patients become more prone to, and monitoring potassium concentrations daily until they, too, are remaining stable.
