Dozens of dog lovers and their four-legged friends gathered on Palmer St. in Harvard Square last month for a “Summer Pawty,” featuring costumes, treats, and even doggie portraits.

The event kicked off with a stroll around Harvard Square followed by a costume contest, which saw creative costumes including a pumpkin, duck boat operator, and a doggie batman. The winner of the contest received a Harvard Square gift basket containing gift cards and treats for both the owner and pup.

Vendors at the event, as well as event co-sponsors Tandem Vet and Cambridge Veterinary Care, provided treats, “pup cups,” toys, and other goodies for the dogs.

Local artist Bridget Foster Reed works on one of the several dog portraits she produced for event attendees.

The event was not the first dog costume contest to hit Harvard Square, but it was the first such event since the Covid-19 pandemic. Denise A. Jillson, executive director of the Harvard Square Business Association, said she was was “just so excited” to bring a dog party back to the Square.
