I don't know about Yorkies and cockatiels, but our mutt reluctantly accepted that Fred (son's cockatiel) was part of the family and would have to be tolerated even when Fred was walking down the middle of the narrow hallway forcing the dog to wait for him to make his slow waddling way from one room to the next or when the bird would finally get airborn and dive at him from above. He never tried to attack it. |
