The animal shelter bosses have now banned anyone under 21 from adopting a miniature pup, following a growing trend of young women dumping their full-grown dogs when they're sick of caring for them.

Hilton was investigated last year after admitting that she owned 17 dogs, allegedly breaking U.S. laws that ban non-breeders from having more than three per address.
