Ontario Yorkie Lulu, standing only 3 inches tall in Loretto, stuns locals and Guinness World Records with her outsized sass. At just 4 months old and less than a pound, Lulu’s feisty bite and miniature frame outdo current record-holder Pearl the chihuahua.

Record-chasing Lulu’s bite matches her pint-sized bark, as owner Kim Passero recalls her swatting and nipping after a dreaded first bath. Tiny dog breed fans now await Lulu’s first birthday, when Guinness may officially crown this spunky Yorkie the world’s smallest boss.
