🔍 Assessing Cavalier King Charles Spaniel Body Condition (BCS)
Scale weight is only one component of body composition. A Cavalier King Charles Spaniel in ideal body condition (BCS 4-5 out of 9) demonstrates:
- Rib Palpation: Ribs easily felt with gentle pressure, without excess fat cover.
- Top-Down Silhouette: Clear, discernible hourglass indentation behind the ribcage.
- Lateral Abdominal Tuck: Upward curve of the belly when viewed from profile.
⚠️ Excess Weight & Cavalier King Charles Spaniel Health
Excess body fat acts as an endocrine organ, secreting pro-inflammatory cytokines that accelerate cellular aging and joint cartilage breakdown.
For a Cavalier King Charles Spaniel, keeping weight near the optimal average (16 lbs male / 16 lbs female) lowers the lifetime risk of Mitral Valve Disease and Syringomyelia.
