Chronic kidney disease is one of the most common age-related conditions in dogs, progressing through IRIS stages with increasing welfare impact from uremia, hypertension, and anemia requiring stage-appropriate management.
CKD welfare impacts accumulate gradually as kidney function declines. Early stages may be subclinical, but progressive uremia causes nausea, lethargy, and the reduced quality of life associated with chronic systemic illness. Hypertension damages other organs silently. Anemia causes fatigue that limits activity and enjoyment of previously rewarding interactions. In advanced CKD, the constellation of uremic symptoms - nausea, neurological changes, pruritis, and weakness - significantly impairs quality of life. Welfare-centered CKD management uses the IRIS staging framework to match intervention intensity to disease severity, monitors response using validated quality-of-life tools, and includes honest end-of-life planning as disease progresses.
