A large crocodile was recorded swimming calmly through the Puerto Vallarta Marina (Mexico) with a lifeless black dog wearing a red collar in its mouth, horrifying onlooking tourists. New Zealander Tim Weston was vacationing with his wife when the attack happened, and he described how 'the crocodile kept the dog in its mouth for ages, not moving at all'. He said the dog belonged to the local bike shop's owner."
