Why is treating hypertension important in dogs with CKD?

• A. It has no impact on kidney disease
• B. It only affects blood pressure without end-organ risk
• C. It increases the risk of retinal detachment
• D. Treating hypertension reduces the risk of end-organ damage such as retinopathy and CNS events

Answer: (D)

Managing high blood pressure in dogs with CKD is crucial because elevated pressure damages tiny vessels throughout the body. In CKD, mechanisms like RAAS activation and fluid retention raise blood pressure, and the resulting hypertension harms sensitive organs. The retina can develop hypertensive changes that lead to retinopathy and even retinal detachment, while the brain becomes vulnerable to intracerebral hemorrhage and other CNS events. Lowering blood pressure protects these end organs and also slows kidney damage by reducing glomerular pressure and proteinuria. So treating hypertension directly reduces the risk of serious eye and brain complications, making it the best approach for dogs with CKD.
