Socialite Paris Hilton is determined to give her dogs the same luxurious lifestyle she enjoys herself - so she has built them a miniature version of her Los Angeles mansion.The 26-year-old heiress had a second home constructed in her garden and filled it with matching furnishings to the main house - so her pack of pampered pooches would feel comfortable.The Simple Life Star says, "I have 17 dogs. So I built a doggie mansion in my backyard. It's a replica of my house with a chandelier and the same furniture.They all live there".Meanwhile her boast 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 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.
