Just when you thought the poor girl's PR troubles couldn't get any worse, now the Humane Society is on her case for reportedly buying a $3,000 Yorkshire Terrier with little thought to its origin or proper care.

Britney "is setting a damaging example to the public," thunders the Humane Society's Stephanie Shain in a press statement. "Most dogs sold in pet stores come from puppy mills -- factory-like facilities, churning out purebred and 'designer' puppies in large numbers. Puppy mills look only to make a profit; commonly disregard the dog's physical and emotional health; and do not adhere to sound breeding practices."

As lamentable, according to Shain, is the insouciance with which Britney apparently made her puppy purchase: "Choosing a dog is a major lifestyle decision that should not be taken lightly. We suggest that people take time to choose a member of their family, and to be sure they are working with a reputable breeder."

Taking adequate time to expand one's family? Working with a reputable breeder? Methinks the Humane Society is barking up the wrong Britney.
