Britney Spears has come under fire from an animal rights group in Los Angeles after choosing to buy a new $3,000 (GBP1,500) dog from a pet store. The Humane Society U.S. officials claim the pop superstar should have spent more time picking her pet. Spokeswoman Stephanie Shain tells U.S. TV news show Entertainment Tonight, "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... Ms. Spears is setting a damaging example to the public. "Most dogs sold in pet stores come from puppy mills - factorylike 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."
