Costumed dogs of all shapes and sizes (and their human best friends) are welcome to Founder’s Square on Oct.26 from 5-7 p.m. for a giggle-inducing canine fashion show, followed by doggie treats at Slater’s Yappy Hour. The Gulf Coast Humane Society will be on site for those looking to adopt a pet or to support the no-kill animal-welfare nonprofit. Folks from Royal Paw Grooming & Boarding also will be on hand promoting their products and services. Admission is free. Hosted by the Babcock Ranch Residential Association.
