Call it a ceremonial pup drop.

Charlie - a service dog being trained to work with veterans - dropped the ceremonial puck at Barclays Center on Thursday night. Charlie is a black labrador retriever training with America's VetDogs, which pairs service dogs with veterans who have vision or hearing impairments, or PTSD. The Islanders are raising money for the organization through the team's pucks and paws calendar, which is on sale now.
