What is the differential diagnosis and diagnostic approach for PU/PD in dogs?

Question

Accepted Answer

The provided sources do not contain information about the differential diagnosis or diagnostic approach for polyuria/polydipsia (PU/PD) in dogs. The sources cover paroxysmal exertional dyskinesia in a Welsh Terrier, Eisenmenger syndrome with patent ductus arteriosus, proliferative urethritis, a urinary bladder sarcoma case, and primary orthostatic tremor in dogs — none of which address PU/PD evaluation. Would you like guidance on a related topic covered by these sources, such as the diagnostic workup for lower urinary tract obstruction in dogs?
