Kristin Cavallari headed to the local Petco yesterday in Santa Monica, California for some supplies. Kristin has been a known dog lover for sometime and got a puppy in 2006. She often carries the dog in a carrier but not today. Kristin once famously left a dog, Bentley, with ex-boyfriend Brody Jenner and later wore a t-shirt saying “You Can Have Him.” She has obviously replaced Bentley and was picking up supplies for her latest pet.
