Bailey, an 8-month-old German Shepherd, adventured an estimated 10 miles across two states and one river all on his own.

He was found by Dr. Matthew Morgan, chief of surgery at the Veterinary Emergency and Referral Group. Dr. Morgan says what happened with Bailey was a miracle.

“This could’ve gone really, really poorly for Bailey so it’s more the people he met along the way were the right people,” said Dr. Morgan.

Dr Morgan, along with locals who tried helping the pup along the way, say Bailey escaped from a yard in Red Hook on May 8. Bailey was caught on camera swimming through the East River in Manhattan, where he was rescued by a paddleboarder who helped free him.

Authorities tell News 12 that Bailey was then spotted at the entrance of the Brooklyn Battery Tunnel and even made his way over to the Holland Tunnel, where the dog was caught on camera running through the tunnel.

After a week of travel for the dog, News 12 was told that Bailey was rescued by the Port Authority police, when he finally made his way to Dr. Morgan, unfortunately with some injuries.

Harriett Zucker was Bailey’s trainer before his great escape, and is working to find him the perfect home following this intense adventure.
