Can you please supply me with any information on King Charles Puppy litters available now or soon or would seriously consider an older dog, we are in Thirsk, north yorkshire

I don't mean this to sound rude, but many people who ask for information about King Charles Spaniels actually mean another breed, the Cavalier King Charles Spaniel - so I've given you details of both breeds! If you contact the breed clubs listed at the bottom of those links you'll be advised of reputable breeders and the required health tests. (Cavaliers are prone to heart problems among other conditions, and poorly-bred ones can die very young.)

If it's really the King Charles you're looking for, be prepared for a long wait - they're not a very common breed.
