Update 9:30AM Found the hound!
Thanks to several Beach Drive neighbors… Charlotte, Judy, Kevin, Jeff, guy with stroller, lady with dogs, passing cars with sightings, etc. we managed to track Brownie down and reunite him with relieved owners.
Reports are coming in of a puppy who looks to be about 40 pounds and a lab-sheppard mix, running scared around Jacobson and Beach Drive. He is too frightened to come when called.
