Jack Russell Terrier vs Cavalier King Charles Spaniel - Breed Comparison

The origin of the Cavalier King Charles Spaniel goes back many centuries. It was in 1928 that this spaniel breed was separated from the smaller King Charles and these were particularly popular with royalty in England.

In fact, Mary, Queen of Scots had one of these spaniels who accompanied her to her beheading. It was her grandsons who gave their name to the breed, and King Charles II, who reigned from 1660 to 1685 kept these dogs. After Charles II's death, the dog’s popularity waned somewhat. The dog was later bred with pugs giving them the familiar features they have today, such as the domed head and the shorter nose.

Interest in the breed revived, and a breed -club was established, drawing up a breed standard. Finally, in 1945, the Cavalier King Charles Spaniel was recognized as a separate breed.

Ear Checks:
