The Cavalier King Charles Spaniel: Royally Gentle, Endlessly Loving
Named after King Charles II of England, the Cavalier King Charles Spaniel is the definition of a noble companion. With their silky, feathered coat, soulful eyes, and sweet temperament, Cavaliers are one of the most affectionate breeds in existence. They're equally happy on a long walk or curled up beside you on the sofa, and they deserve gear that matches their gentle, elegant nature.
About the Cavalier King Charles Spaniel
Typical weight: 12–18 lbs
Typical harness size: S (lighter Cavaliers) or M (standard adults)
Energy level: Moderate. They enjoy daily walks and playtime but aren't overly demanding
Coat: Silky, medium-length with feathering on the ears, chest, legs, and tail — beautiful but tangles easily
Common health note: Cavaliers are prone to Mitral Valve Disease (MVD), a heart condition that affects the majority of the breed by age 10. This makes low-stress, comfortable gear especially important — anything that causes pulling, straining, or discomfort puts unnecessary pressure on their cardiovascular system. A well-fitted chest harness keeps walks relaxed and strain-free.
What Your Cavalier Needs
A gentle, well-fitted chest harness. Cavaliers are soft-natured dogs that respond poorly to any discomfort or restriction. A lightweight, properly fitted step-in harness that distributes pressure evenly across the chest — with no neck pressure — is the kindest and safest choice for this breed.
A harness that protects their feathered coat. That silky feathering on the chest and legs is one of the Cavalier's most beautiful features — and the most vulnerable to tangling. Smooth-lined harnesses with no rough edges or velcro near the chest are essential to keep their coat looking its best.
A layer for cool weather. Cavaliers have a medium-length coat that offers some insulation. However, they still appreciate a cozy fleece on cold days — especially older Cavaliers who may be managing heart conditions and benefit from staying warm.
