Blenheim Dog, or MARLBOROUGH DOG, a small and very beautiful variety of spaniel, much resembling the King Charles breed in form and general appearance, but differing in the colour, which is white, with orange or flame-coloured markings. In weight it should not exceed 5 lb. The Blenheim spaniel is the Pyrame of Buffon. It derives its English name from Blenheim Park, in Oxfordshire, where the breed was a favourite one from the beginning of the 18th century.
