How much should a Cavalier King Charles Spaniel weigh?

The ideal adult weight range is 5.9–8.2 kg (approximately 13–18 lbs). Males typically sit toward the upper end and females toward the lower end. Body condition score is a more reliable guide than scale weight alone — a dog in the range but with no visible waist may still be overweight for their frame.

My Cavalier weighs 9 kg — is that too heavy?

9 kg is above the upper end of the breed's ideal range (8.2 kg). While individual variation exists, a weight this far above the range warrants a veterinary check to assess body condition and rule out any underlying health factors. A modest weight reduction plan may be recommended.

Do Cavaliers naturally look a bit chubby due to their coat?

Their feathered coat can give a soft, rounded appearance even at an ideal weight — but this should not be confused with healthy body condition. Always assess ribs and waist by feel, not by appearance through the coat. A Cavalier at an ideal BCS of 4–5 should have clearly palpable ribs with light pressure.
