A fine and rare dog grate made in the Chippendale Rocco manner probably mid-Georgian. 

The dog grate is an interesting example with large cabriole brass legs topped with flamed urn finials.  The shell front motif flanks the serpentine brass apron under the bowed firebars.  The back of the firebox is topped with a motif depicting two winged Griffins with a paw resting on a lit torch in the Greek revival style. 

Made in England during the 19th century.

A similar grate can be see in Hogarth's painting of Marrriage a la Mode.
