Overview of Canine Nutritional Secondary Hyperparathyroidism
Nutritional secondary hyperparathyroidism is a nutritional/metabolic disorder caused by an elevation of parathyroid hormone (PTH), usually secondary to poor nutrition. It is the body’s normal compensatory response to nutritionally induced hypocalcemia, or low calcium.
Inadequate diet stimulates increased PTH release through low calcium, high phosphate and low vitamin D. All meat or all grain diets are the most common cause.
This disorder is seen in both male and female dogs and is most common in young dogs. It can affect any breed.

Home Care and Prevention
Administer all medication/supplementation and dietary recommendations as directed by your veterinarian. Reevaluating laboratory data and radiographs at intervals set by your veterinarian are helpful in assessing improvement and response to therapy.
Animals without severe bone deformities have a good prognosis. Bones often normalize within a two to three months period. Fractures may have delayed healing.
Feeding your dog a proper diet can prevent this disorder.
