We can judge whether the long-necked turtle knows the owner through the following points:

1. When the owner is feeding the long-necked turtle, the long-necked turtle not only does not run , but will speed up and run to the owner's side.

2. If the snake-necked turtle is placed on the ground, they will not crawl towards strangers, but will only follow the owner's footsteps.

3. When the snake-necked turtle feels danger It will shrink into the turtle shell. If the owner goes to the side, it will not shrink into the turtle shell, then it can be a big indication that the long-necked turtle has regarded you as its owner.
