The best way to protect fur babies in this overbearing heat? Throw them a party. It worked for Mix 104.1’s Kennedy Elsey, who hosted the annual Canines and Cocktails event at the Seaport Hotel, where two-legged creatures enjoyed frosty and refreshing cocktails while their pups frolicked and feasted on specially made treats crafted by the Seaport’s executive chef Richard Rayment. Among the dog lovers who stopped by were TV reporter and anchor Janet Wu and personal chef Jen Royle. The event was a benefit for Great Dog Rescue New England.
