Cavalier King Charles Spaniels are very beautiful dogs. They are also considered to have a wonderfully plumed tail that has a hypnotizing wag. Cavaliers are usually small dogs, with a sweet expression emanating from their dark round eyes. They have the habit of following their owners around everywhere!  These dogs have an average litter size of 3.4 puppies. However there are some births that have brought about 9 puppies! When they grow up and when they are trained, the breed makes good guard dogs for they will announce to their owners when a visitor is coming. Remember that breeders know the personality of each puppy, they know best more on matching the puppy to its new family.
