Jennifer Aniston and Justin Theroux adopted a pit bull mix. They named the pup Sophie, after Sophie's Choice because she admits it was a hard decision choosing just one puppy. Like in the movie, the mother had to choose which of her children would be killed and which would be sent to labor camp.
Sophie is a cute black and white puppy that she says has gotten into everything.
Sophie seems to get along just fine with Dolly, Aniston's German Shepherd.
So, as you can see, pit bulls and mixes are favored among celebrities just as they are everyone else.
