Paris Hilton's dog love has landed her at the centre of a new Los Angeles Department of Animal Services investigation, after the heiress boasted about owning 17 pets on a TV show. The socialite told chat show host Ellen DeGeneres all about the extent of her pooch collection on the comedienne's show on Monday (11Feb08) - not realising it's illegal to have more than three dogs at any one non-kennel, non-breeder,residential address in Los Angeles. Animal Services sources tell TMZ.com that bosses of an animal rescue organisation took heed of Hilton's dog boast and complained to the officials, who paid her a visit on Tuesday (12Feb08). The website reports Animal Services representatives turned up at Hilton's home, but Paris and her dogs were not there. They left a message with a maid and now plan to return to conduct a full inspection.
