Check-ups in dogs with stable CKD: what to monitor
10-year-old Beagle with IRIS stage 3 CKD, proteinuric, on a renal diet and benazepril for 4 months. He is stable and attends a check-up.
Which follow-up plan is most appropriate?
chevron_right Show answer and explanation
A. Creatinine only, once a year, because it is the only marker of progression
An annual check is insufficient at stage 3, and creatinine alone misses treatable problems such as proteinuria, hypertension, hyperphosphataemia or anaemia.
B. Every few months: weight, body and muscle condition, blood pressure, creatinine (or SDMA), phosphate, potassium, haematocrit, urinalysis with UPC and, where appropriate, urine culture
Correct. Each parameter guides a decision: phosphate, the binder; UPC, the ACE inhibitor dose; potassium and creatinine, its safety; weight and muscle mass, intake. After each treatment change, an earlier recheck is done.
C. Renal ultrasound at every check-up to measure progression
Ultrasound is useful at diagnosis and in acute deterioration (obstruction, pyelonephritis), but it does not replace functional parameters and is not repeated routinely to track progression.
D. No check-ups are needed if the dog is well at home; return only if signs appear
Hypertension, proteinuria and hyperphosphataemia cause no signs until advanced stages; waiting for signs misses the window for action.
lightbulb Key takeaway
As a guide: stable stage 2 every 6 months, stage 3 every 3–4 months, stage 4 more often, and always 1–2 weeks after starting or adjusting an ACE inhibitor or ARB. Record weight and muscle condition: cachexia worsens prognosis.
