The Cavalier King Charles Spaniel is a breed that The Kennel Club classifies as a toy dog. It is a small spaniel that comes from the United Kingdom, growing in popularity in the United States since the turn of the 21st century. This dog currently ranks as one of the top 20 most popular purebreed options in the U.S. right now.
Cavalier King Charles Spaniels are noted for their unique coat coloration, of which the breed standard recognizes four colors: chestnut and white, tricolor, black and tan, and ruby. Most of the animals are very affectionate, work well with children, and manage relationships with other dogs or pets with little difficulty. It is a highly social breed, so it does require a lot of human interaction to maintain a healthy mental state.
Because it is a family dog, you should not leave them alone for long periods because it can trigger significant levels of anxiety in the animal. The average lifespan for the breed is under 10 years.
