The parenting skills of Britney Spears are being called into question once again, but this time, the criticism isn't revolving around dropping Sean Preston or neglecting Jayden James. This time she's been voted the world's worst celebrity dog owner by two dog magazines.

"Britney Spears was the overwhelming choice," Hilary O'Hagan, editor of The New York Dog and The Hollywood Dog magazines, said in a statement.

"She once had three Chihuahuas... and never left home without at least one of them on her arm. As soon as she met [Kevin Federline] and had kids, (the dogs) disappeared."

Her pants seem to have done the same.

Britney's former BFF, Paris Hilton, placed second for "treating her dogs like accessories."

Oprah Winfrey, who owns five dogs, was voted this year's best celebrity dog owner. The talk-show host replaced 2005 winner Joss Stone, and beat out fellow dog owners Tori Spelling and Nicollette Sheridan.

We're not entirely sure that the criteria are here. Brit was named worst dog owner for leaving her dogs at home, and Paris was named second worst dog owner for toting her dogs everywhere like purses? These publications obviously need to get their points straight before hastily giving Britney and Paris such bad publicity.

Oh, who are we kidding, we fear for any dog that happens to come in contact with either celeb. Same goes for this pathetic Paris Hilton pussy.

Also, we're not sure that Spears' Chihuahua, Bit-Bit (pictured) would fare well at Hyde, where Britney's been spending most of her time these days.

Actually, it's probably good that Brit leaves her pooches at home... as long as Natasha Lyonne isn't dog-sitting, of course. What whuuuut!
