My rescue Shih Tzu doesn't play with any toys either. I think it's because he was probably never introduced to them.
I only got him when he was almost 3 years old. I know that's not relating to what you said. But my mom's/my dauxie, GiGi ( God rest her soul ) never hardly played with toys and my mom had her since she was 8 weeks old. Sorry, no suggestions, just comments.
