What owners actually say
Cavalier owners are devoted to the breed’s gentle nature — and consistently stress the importance of understanding the cardiac health reality before getting one.
- Health reality
The heart disease reality is the biggest surprise. Many owners say they weren’t fully prepared for the emotional and financial weight of managing MVD as their Cavalier aged.
- Alone time
Cannot cope with being left alone. Owners who work full-time consistently say a dog walker, daycare, or a second dog is essential — not optional.

Excellent apartment dogs. Calm indoors, minimal exercise needs compared to other breeds, and quiet enough for building living when given companionship.
- children
Universally praised with children. Patient, gentle, and unflappable — owners describe them as ideal family companions.
- Training
Eager to please and responsive. Owners find them easy to train with positive reinforcement and describe recall as reliable compared to other small breeds.
- General
Owners describe Cavaliers as the most devoted companions they’ve ever had. The cardiac health commitment is real — but most say the breed is worth every bit of it.
