Teddy will recognize his owner when he is one year old. Usually young Teddy can accept new owners faster, while adult Teddy will be much less receptive to new owners, so the owner needs to spend more time and energy. You should have more contact with it, play with it more, and feed it yourself. Teddy is very smart. As long as you treat it sincerely and feel the careful care of its owner, it will slowly trust its owner and begin to recognize its owner.
How to make an adult Teddy recognize its owner quickly:
1. Prepare a warm kennel for Teddy so that it can relax its vigilance and feel safe.

2. You need to accompany it more and take it out for walks more often. Dogs usually like to go out.

3. Make more physical contact with it and gently touch it, which will enhance the relationship between each other.

4. Feed it at regular times and at designated times so that it can develop a habit and it will become dependent on its owner.
