My cousin's dog is allergic to red meat. It turns out she was bitten by a paralysis tick over east and that causes mammalian meat allergy in animals and people. She can eat chicken and fish but no red meat.
We had a male Muscovy duck called George who was afraid of water. He used to hide under the back veranda when it was raining and wouldn't go in the pond. We got him a girlfriend called Pinky and she loved water. George loved her and followed her everywhere except into the pond. When George got too amorous, Pinkie would hop in the pond and George would walk around it watching her.
