The Hawaiian Humane Society is investigating after a puppy was found chained to a tree in Windward Oahu.
The dog was picked up at Waiahole Beach Park Friday afternoon. The society says he was not there the day before.
The chain was embedded in his neck, causing an infection, a spokeswoman said. Veterinarians removed the chain and treated the wound.
The puppy does not have a microchip.
