What are dog breeds?
Dog breeds are basically a "type" of dog. Some examples are Jack Russell Terrier, Fox Terrier, Puli, Afghan Hound etc. etc blah blah blah! Whereas such titles as sheepdog, terrier, spaniel, etc. relate more to the breed's original/current use. Take the King Charles Cavalier Spaniel. They are a spaniel. The rest of the name, Cavalier King Charles relates to the brreds specific use so that if there were ever a cavalier king Charles terrier there would be a difference.
