Symptoms and Treatment of Kidney Failure in Dogs
📝 Summary
Chronic kidney failure is common in older dogs and is the late stage of kidney disease, usually ending in uremic syndrome. It can't be cured, but medication, a kidney prescription diet, and managed fluids can add months or years of quality life, so senior dogs need regular checks.
1 Causes
Kidney failure usually arises from kidney disease; renal failure is the late-stage sign of canine kidney disease.
2 Clinical Signs
(1) Azotemia and uremia are staged. (2) Azotemia may show no obvious signs and be found only on blood work. (3) Uremia means multi-system poisoning: polyuria, thirst, poor appetite, weight loss, lethargy, pale mucus, ulcers, vomiting, sometimes seizures. (4) Azotemia raises blood urea; creatinine or other non-protein nitrogen appears. (5) Uremia shows raised creatinine and BUN on blood tests.
3 Prevention and Management
(1) Treatment rarely cures it, but the right medication can raise quality of life for months or years. (2) A proper kidney diet meets nutrition and energy needs, eases uremia, and corrects electrolyte, vitamin, and mineral imbalance, slowing the decline. (3) A vomiting dog can still drink to stay hydrated and avoid stress. (4) With uremic failure, allow moderate water, keep normal protein, and limit phosphorus; restrict sodium if blood pressure is high to avoid potassium loss. Consider erythropoietin plus vitamin D.
4 Advice for Owners
The kidneys excrete protein waste and balance the body’s acid-base and red-cell production. Signs appear only after widespread kidney damage, so senior dogs need regular health checks.
