In fact, this is such a common cause that lymphoma must be pursued rigorously in any dog with hypercalcemia before another diagnosis is considered.

The small osteoclast pool results from feeding a high concentration of dietary calcium during the nonlactating period, which suppresses secretion of PTH by the parathyroid gland and stimulates secretion of calcitonin by parafollicular C cells. The disorder is diagnosed by finding of low concentrations of PTH in the serum, and is treated as is iatrogenic hypoparathyroidism (see above). This protocol effectively supports serum calcium concentrations while waiting for oral vitamin D and calcium treatment to have effect. Hypocalcemic animals should, therefore, receive parenteral calcium support during the initial posttetany period. Calcium-containing crystals, isosthenuria, hematuria, and/or pyuria can be present. 4 CONTRAINDICATIONS.

This calcium preparation must be given slowly and the veterinarian should monitor for cardiac arrhythmia. Therefore, the nerve fiber becomes highly excitable, sometimes discharging repetitively without provocation rather than remaining in the resting state. Exchange resins may be effective to control mild hyperkalemia, but have little efficacy or indications in the management of potassium associated cardiotoxicity.
