Toy Small adult scale

Cavalier King Charles Spaniel.

Warm, gentle and sociable, Cavaliers are companion dogs with a sporting side. Many are equally pleased to share a country walk or a comfortable sofa and thrive on being part of family life. Their loving nature comes with a need for company, coat care and careful heart, eye and neurological health checks.

At a glance

Typical adult pet: Roughly 5–10 kg · Exercise: Around 1 hour. These are broad planning ranges, not targets or guarantees.

What living together may involve.

Often sociable and people-focused; prolonged time alone may be difficult.

Grooming

Frequent brushing plus regular ear and coat checks.

Activity

Around 1 hour. Age, fitness, health, weather and the quality of enrichment can change what an individual dog needs.

Planning

Plan particularly for company, coat care and health screening.

Training

Use kind, reward-based training and build skills gradually. Breed can suggest inherited tendencies; it cannot determine a dog’s personality.

Real-world size

Pet range first.
Show standard second.

Roughly 5–10 kg is a rounded planning range for ordinary adult pets. RKC show standard: 5.4–8.2 kg. Neither figure decides whether an individual dog is healthy or proves pedigree. A veterinary body-condition assessment is more useful than aiming for a number alone.

Choose health and function.

Ask for the health tests relevant to both parents and verify results independently. Avoid exaggerated features that compromise breathing, movement, eyes, skin or ordinary activity. A responsible breeder or rescue should welcome careful questions.

Children, other animals, time alone and first-time ownership cannot be decided by breed label alone. Temperament, early experience, health, training, management and the household all matter.
