Jake Gyllenhaal: The Prince of Petco

Jake Gyllenhaal picks up dog supplies at the Petco pet store early Monday morning (January 5) in Brentwood, Calif.

The 28-year-old Prince of Persia: Sands of Time actor picked up Castor & Pollux‘s Organix Adult Canine Formula, which is made with organic chicken, brown rice and flax (no pesticides, no growth hormones, no synthetic fertilizers and no antibiotics). Probably for his dog, Atticus!

Sneakers by Nike, Sweatpants by Adidas Y-3.

Last night Jake and girlfriend Reese Witherspoon went to the Lakers game.
