The canine remnant kidney model is fundamental to understanding the relationship between hypertension and chronic kidney disease (CKD). This study aimed to create a 1/16 remnant kidney model and to determine whether blood pressure (BP) control affects the progression of CKD. A group of dogs received BP treatment (group A) and another received BP treatment except for the first 2 weeks (group B). The remnant kidney model was induced using a two-step subtotal nephrectomy method; dogs received antihypertensive therapy. Systolic BP, blood urea nitrogen, serum creatinine, urinary protein, and creatinine levels were measured weekly. Kidney tissues were obtained at the conclusion of the study. Systolic BP was controlled to
