It’s a case of “Canines against Cancer.”

The third annual Florham Park “Bark for Life,” a canine event to help fight cancer, returns to the Florham Park gazebo at 111 Ridgedale Ave. on May 21, from noon to 3 p.m.; rain date May 22.

The American Cancer Society fundraiser will once again be hosted by co-founders and Hanover Park High School juniors Brendan Sardo, Jason Sardo and Derek Saul, as well as 105.5 FM WDHA radio personality Terrie Carr.

The event is open to dogs and their owners, and features contests for the dogs, demonstrations, craft and shopping vendors, food, music and other fun activities.

The objective is to build on the $25,000 raised to help fight cancer from the past two events, and provide a unique day out for dogs, canine caregivers and the community.
