The earliest is probably Blighttown, where you will be able to pick up an Eagle Shield. It blocks only 95% of physical damage, but is light for a greatshield.

Next up, you'll be able to buy a Tower Shield from the Crestfallen Merchant, the most stable non-unique shield in the game.

Once you get to Anor Londo, you can pick up Havel's Greatshield and craft the Greatshield of Artorias.

These are the main ones you probably will want, but there are a couple of more you can get, mostly from enemies, if you feel so inclined.
