What is pet kidney disease?

Chronic kidney disease (CKD) in cats and dogs is a common medical condition in middle-aged and older pets. Impaired kidney function can affect water regulation, electrolyte balance, and waste excretion. If not managed promptly, it can eventually develop into severe renal failure, which can be life-threatening.

Causes and risk factors

  • Congenital anomalies/genetics
  • Immune system deficiency
  • Acquired: diabetes, aging, kidney inflammation, and medication side effects

Main symptoms of kidney disease

Symptom classification Specific manifestations
Early symptoms
  • Obvious thirst
  • Increased urination frequency but decreased volume
  • Decreased activity and fatigue
  • Pale mucous membranes (anemia)
Advanced symptoms
  • Decreased appetite and significant weight loss
  • Bad breath, mouth ulcers
  • Hypertension, vomiting and diarrhea
  • In severe cases, heart failure and pulmonary edema may occur

Diet and dietary recommendations

  • Choose high-digestibility, high-quality meat protein foods and avoid low-absorption plant proteins
  • Adjust and limit the intake of phosphorus, potassium, and sodium to reduce the burden on the kidneys
  • Reduce fat and follow a renal formula prescribed by your veterinarian or nutritionist
  • BARF (raw meat) and fresh food can be given in appropriate amounts according to the stage of the disease
Common myth: Can a low-protein or purely vegetarian diet prevent kidney disease? In fact, cats and dogs need sufficient high-quality animal protein to maintain good health. Excessive plant protein can actually increase kidney filtration pressure.
If function has declined, consult a veterinarian to evaluate protein intake at each stage.

Daily care & prevention tips

  • Ensure fresh drinking water is always available (encourage frequent drinking and monitor water intake and urination)
  • The staple food should be highly digestible and should not be replaced with inferior feed at will.
  • Regular health check-ups, urine and kidney function indicator monitoring
  • If you have chronic diseases or are an elderly cat or dog, it is recommended to track kidney health every six months.

Veterinarian's caring advice

While renal failure is currently irreversible, its progression can be effectively slowed through healthy diet, daily health monitoring, and regular exercise. If any unusual symptoms occur, please take your pet to a veterinary clinic for a thorough examination. Early prevention and treatment are key to protecting your pet's health!

FAQ

  • Q1: What should I do if I find that my pet’s daily water intake and urination have increased significantly?
    It is recommended to immediately arrange for renal function and urine index tests to rule out kidney disease.
  • Q2: Can cats and dogs with kidney disease still eat fresh food or BARF (raw meat)?
    In the early stages, you can eat high-quality meat in moderation and control phosphorus and potassium. For advanced stages, you should mainly use kidney disease formula food and follow the veterinary adjustments.
