Health to watch

Cavaliers are predisposed to mitral valve disease (a heart condition) and certain neurological issues such as syringomyelia, as well as ear and eye conditions. Regular veterinary check-ups, including heart monitoring as they age, are an important part of responsible care. Keeping a complete, shareable health record of cardiac findings, weight and any symptoms helps your vet track these breed-specific concerns. Ask your veterinarian about appropriate screening and what signs to watch for at home.

Grooming & care

The Cavalier's silky, medium-length coat with feathering needs brushing several times a week to prevent mats, especially behind the ears and on the legs. Check and clean the long, hairy ears regularly to reduce infection risk, and keep nails trimmed and teeth brushed. Occasional baths and routine grooming keep the coat healthy and comfortable.

Exercise & temperament

Cavaliers have moderate energy and are happy with daily walks plus play and cuddle time, making them flexible companions. They are friendly, gentle and eager to please, responding beautifully to reward-based training and early socialisation. Because they form strong bonds, they can be prone to separation anxiety and prefer not to be left alone for long periods.

Nutrition

Feed a complete, small-breed-appropriate diet in measured portions, as Cavaliers can gain weight easily and excess pounds strain the heart. Account for training treats and monitor body condition regularly. Confirm an ideal weight and feeding plan with your veterinarian, especially if heart disease is a concern.

Can Cavaliers be left alone during the day?

Cavaliers bond very closely with their people and can struggle with being left alone for long periods, sometimes developing separation anxiety. Gradual training, enrichment and, when needed, daytime company or a dog walker help them cope.
