Call her Sara - come closer and I will tell you a little story.
While the Duke of Marlborough was fighting the Battle of Blenheim, the Duchess, Sara, was anxious for news and kept constantly stroking the head of her little red and white spaniel.
When news of the victory was announced the spaniel gave birth to five puppies, all of which had the thumbprint of the Duchess on the top of their heads. This became known as the Blenheim spot or lozenge as we now know it.
So - Sara!
Actually I think that photo is of a King Charles Spaniel which are smaller and have a more pushed up face than Cavalier King Charles.
Have a look at this site and scroll down to Show Information, then photos, then down to Southern CKCSC and there are lots of photos of Blenheim cavaliers.
I bet she is adorable louise ,:-) x
Lankeela , I googled for Blenheim and that pic said Blenheim King Charles Spaniel , but most of the pic results were of cavaliers . :-)
