Even celebrities need a non-human best friend. Here are a few glimpses of the pets of famous (or semi-famous) people.
President Barack Obama runs away from the family dog, Bo, during a break from meetings on the South Lawn of the White House in May 2009.

Ted Kennedy who was also a fan of the breed.
