Chronic kidney disease is one of the most common conditions in older dogs, causing prolonged welfare compromise if undiagnosed or undertreated. Early detection and management significantly improve quality of life.
Chronic kidney disease in dogs causes progressive accumulation of waste products that the damaged kidneys cannot filter, resulting in nausea, reduced appetite, lethargy, and — in advanced disease — vomiting and neurological signs. Because the disease progresses silently in its early stages, many dogs are not diagnosed until kidney function is already significantly compromised. Annual blood and urine screening in dogs over 7 enables earlier detection when dietary and medical management can most effectively slow progression. Welfare management focuses on maintaining appetite through antiemetics, managing phosphorus through diet, and supporting hydration through subcutaneous fluid administration. Dogs whose chronic kidney disease is well managed can maintain good quality of life for months to years after diagnosis with attentive home care.
