⚠️ Water needs can change significantly during illness or medication. This calculator isn't reliable for those cases — please consult your veterinarian directly.
Note: This calculator is a general guideline only, not medical advice. If your dog suddenly drinks far more or less than usual, urinates frequently, or seems lethargic — contact your veterinarian without delay.
