Hypoadrenocorticism is an uncommon disease caused by insufficient mineralocorticoid and/or glucocorticoid production. The clinical signs are inappetence, lethargy/depression, vomiting/diarrhea, weakness, shivering, polyuria, polydipsia, collapse.
The average age at diagnosis 4-5 years and there is a female predisposition with ~70% of dogs being female. However, in some breeds there is equal male: female frequency (Bearded Collies, Portuguese Water Dogs, Nova Scotia Duck Tolling Retriever and Standard Poodles).
The disease is diagnosed by aldosterone and/or cortisol suppression on an ACTH stimulation test.
Treatment is hormonal supplementation (mineralocorticoids and glucocorticoids):
- Either Fludrocortisone acetate
- Or Desoxycorticosterone pivalate (DOCP) (mineralocorticoid) with Prednisolone
Prognosis is excellent once controlled.
