Justine Smith's Money Works.

From the website:

More recently Justine Smith has developed this theme and has begun producing a series of sculptures covered in (real) money. These have included "A Euro’s for Life Not Just for Christmas", a series of twelve dog sculptures pouncing around a single pound coin. Each dog is covered with a different one of the currencies of the twelve countries that have joined the Euro. She has also produced the "E.U. Ewe", a sculpture of a sheep given a woollen coat made from a thousand pounds worth of Euro notes, and "Sacred Calf" a life sized calf sculpture covered with U.S. Dollars.

This one above is called "Washington", a dog sculpture covered in dollar bills (get it?).
