A guide to diabetes insipidus (DI) in dogs and cats — what DI is (not diabetes mellitus, no high blood sugar, but rather a deficiency of or resistance to ADH/vasopressin), classification of central DI (ADH deficiency from the pituitary) vs nephrogenic DI (the kidney not responding to ADH), clinical signs (extreme PU/PD 100+ ml/kg/day), telling it apart from DM/CKD/Cushing/hyperthyroid, diagnosis via the water deprivation test (mind the safety) + desmopressin trial, treatment with desmopressin acetate (DDAVP) ophthalmic or intranasal, prognosis, plus an FAQ for owners stuck at "drinks a lot but the diabetes test is negative".
