Most dogs of the breed are playful, extremely patient and eager to please. As such, dogs of the breed are usually good with children and other dogs. A well-socialized Cavalier will not be shy about socializing with much larger dogs. (However, on occasion, this tendency can be dangerous, as many cavaliers will presume all other dogs to be equally friendly, and may attempt to greet and play with aggressive dogs.)
Cavaliers will adapt quickly to almost any environment, family, and location. Their ability to bond with larger and smaller dogs make them ideal in houses with more than one breed of dog.
Cavaliers are great with people of all ages, from children to seniors, making them a very versatile dog.
