Yes! Though the these two dogs are similar, they are, in fact, different breeds.
The King Charles Spaniel, also known as the English Toy Spaniel, is the less widely known ancestor of the Cavalier. It is smaller with a shorter, more wavy coat. He is a brachycephalic breed, meaning it's nose is flat, like a pekingese.
The Cavalier is larger, has a longer, less wavy coat and a regular nose.
Both breeds share the same coat patterns and colors, in addition to having similar personalities. This is because they share a common ancestor. The ancestor of these to spaniels was simply a miniature type of working spaniel. Through selective breeding in the late 1600's and crossings with dogs similar to the pug, this spaniel became the English Toy variety. In the 1920's breeders sought to create a line of toy spaniels that looked more similar to the older variety shown in paintings and tapestries, this dog became the Cavalier King Charles Spaniel. Both breeds are recognized by the AKC.
