Companion dog
Cavalier King Charles Spaniel
Cavaliers enjoy close company and exploring on walks. Before choosing a puppy, ask for both parents’ heart results and about syringomyelia in the family. It causes fluid-filled cavities in the spinal cord that can be painful.

Close company with a spaniel’s curiosity
Bred as a companion, a Cavalier often wants to be close to its people. Outside, another side appears: many enjoy following a scent and playing little search or fetch games. This small companion also needs daily exercise and things to do.
Time alone needs to be learned gradually. Begin with very short, calm absences and add time only while the dog remains settled. In a busy home, give it a place where it can rest undisturbed.
Everyday life
The UK veterinary charity PDSA recommends at least an hour of exercise each day, ideally over two walks. Let the dog sniff and occasionally look for a hidden treat or toy. It can play and run in a safely enclosed area. Short trips outside alone will not meet that need.
Cavaliers can be lovely around children when play remains gentle and adults make sure the dog can take a break. Cats and other animals should be introduced gradually. Small pets such as rabbits can trigger its hunting instincts and need a securely separate area.
Staying home alone
Dogs learn to stay home alone in small steps. The RSPCA advises no more than four hours at a time. Puppies and dogs that become unsettled when left alone need shorter absences and gradual practice. Arrange someone to care for your dog when you will be away longer.

Day-to-day care
Silky hair behind the ears and on the chest, legs and tail tangles more readily than the smooth hair on the back. Brush those areas regularly, daily for some dogs. Grass seeds and twigs can catch there after a walk. Professional grooming can help if the coat keeps knotting despite regular care.
Check ears, eyes and teeth routinely too. Moisture can linger beneath long ear flaps; redness, a smell or frequent head shaking warrants a veterinary check. Introduce tooth brushing in small steps, before dental problems become obvious.
Size and build
Cavaliers stand about 30 to 33 cm at the shoulder and weigh 5.4 to 8.2 kg, according to PDSA. They are small without being fragile: the back is level, the chest moderately deep and the fine-boned legs well muscled. Long, low-set ears carry soft feathering, as do the chest and tail. The muzzle should not be extremely short, and the skull should not be strongly domed.

Health
Mitral valve disease is a major concern in Cavaliers. Over time, the heart valve may stop closing properly; a vet often hears a murmur before the dog shows other signs. Coughing, tiring more quickly or breathing difficulty may follow. When considering a puppy, ask to see both parents’ heart results and find out when close relatives first developed a murmur.
PDSA also lists eye and knee problems, Chiari-like malformation (CM) and syringomyelia (SM). CM involves an abnormal shape or limited space at the back of the skull; SM means fluid-filled cavities develop within the spinal cord. Together or separately, these conditions can cause pain and neurological signs. Ask to see both parents’ eye results and DNA results for Episodic Falling and Curly Coat/Dry Eye. The first can cause episodes of muscle stiffness; the second affects the coat and tear production. If magnetic resonance imaging (MRI) results for CM and SM are available, ask what they show and how the breeder used them when selecting the parents.
Frequent coughing, new pain, reluctance to walk or scratching at the air near the neck deserve a veterinary check. A red, painful eye held shut or sudden difficulty breathing needs urgent veterinary care.
