Kansas City, Mo. ? A Kansas City promoter is hoping to break a Guinness world record by parading at least 700 costumed dogs, mostly Chihuahuas, down a city street on Cinco de Mayo.

Promoter Mark Valentine says the parade will introduce Chihuahuas to their cultural heritage while helping The Pet Connection, a no-kill shelter on the Kansas side of the bi-state metro area.

Parade participants will pay a $5 entry fee to benefit the shelter.

Valentine says the world record for most costumed dogs doesn’t specify a breed, and he thinks there will be more than enough entries to break it.

The parade starts at 11 a.m. May 5 in Kansas City’s Crossroads Art District. All canine entrants must be leashed and in costume. Registrations will be accepted onsite.
