The Cavalier King Charles is sweet, gentle, affectionate and very expressive. It is an athletic and energetic dog, without a trace of fear and particularly courageous, which is why it should never be left unattended and without a leash.
They weigh between 6 and 9 kg and differ from the King Charles Spaniel in head shape, with a flatter skull and longer muzzle.

There are four shades : 

1. Blenheim with chestnut patches.

2. Tricolour or Prince Charles, white with black and fiery patches in certain places.

3. Ruby, intense glossy red.

4. Black fire.Their hair is straight, long and silky, slightly wavy but never curly, while the legs, ears and tail are covered with longer hair.To keep their coat in good condition, they need to be brushed 2-3 times a week for a few minutes. It is forbidden to cut their hair.

They are very trainable in basic obedience and highly intelligent with very good performance in agility.

They are prone to gluttony, so special attention must be paid to their diet.
