Sept. 22 might have marked the official end of summer, but the annual Pooch Plunge earlier in the month ushered in the dog days of summer’s end.

This year’s Pooch Plunge at Robert Strange Pool on South 10th Street saw about 300 canines splashing over five days to mark the seasonal closing of the city’s pools.

“The Pooch Plunge was started by the city of Wilmington, and when the YMCA began managing the city pools, we understood right away the impact of the Pooch Plunge,” said Josh Gravette, Nir Family YMCA’s executive director. “It is such a fun way for our community to come together and have fun with our beloved canine friends.”
