This week, we talk to Adam Jacobson, executive vice president at Pet Pantry Warehouse on Grove Street, about New Canaan Dog Days. The hugely popular celebration of dogs, a fundraiser for rescue groups, will be held 11 a.m. to 4 p.m. on Saturday, May 21 at the New Canaan Nature Center. It features games, competitions, family activities, entertainment, and a lot of free swag from premium pet food brands.
