Oprah Winfrey has often used her talk show to highlight the plight of homeless and abused animals. When her pet of 13 years, Cocker Spaniel Sophie (pictured) died in March 2008, she paid her an emotional tribute on the show, saying the dog was her true love and made her a kinder, gentler person.

Britney Spears - Bit Bit
Britney Spears' Chihuahua Bit Bit shot to fame in 2004 when the singer hit the red carpet at an awards show with the tiny dog wearing a $100,000 diamond-encrusted collar.
In those days Spears led the trend of owning "accessory dogs." She dressed up Bit Bit in faux mink coats, and the dog had a "princess bed" to sleep on. Despite, all this pampering, Spears was named the worst celebrity dog owner of the year in a 2006 magazine poll for treating her dogs like accessories.
That was followed by some highly publicized, erratic behavior in 2007 when the pop star reportedly let her new Yorkshire terrier puppy poop on a $6,700 Zac Posen dress during a photo shoot.

The singer has recently spoken about being a "new mom" to fiance Eric Johnson's Airedale terrier Bentley.
