The Residences at Wingate, a pet-friendly senior living community at 235 Gould St., will host a pet costume parade on Saturday from noon to 2 p.m. to benefit the Buddy Dog Humane Society, a Sudbury-based shelter and adoption center for dogs and cats. Area residents are encouraged to dress their pets in costume to compete for hundreds of dollars in prizes. Knots of Fun, an interactive dog toy store in Framingham, will also be on hand to help participants create an original dog toy to take home. To RSVP or for more information, call 781-455-9080.
