The 19th annual parade Sunday in St. Louis had an official count of 1,326 costumed dogs, far surpassing the Guinness World Record of 603 set in Japan in May 2011, the St. Louis Post-Dispatch reported Monday.
"We are the largest pet parade in the country, and there's no reason why we shouldn't be in the Guinness Book of World Records," said Tracie Quackenbush, the executive director of Open Door Animal Sanctuary, which receives proceeds from the parade.
Sponsor Nestle Purina PetCare Co. said video from the event is being submitted to Guinness.
