I buy xs and small dog toys for my hedgehog. He loves it! He likes plush toys, dog balls and chewing ropes. We have a lot of fun playing with them. I'm trying to teach him how to play fetch, lol...
Maybe you should read some reviews before you decide which dog toy to buy. I read that with plush toys he can rip it open and eat the filling. I don't let him play with them alone.
I found a good listing here: https://dogtoysadvisor.com/best-dog-toys/
Be careful and have fun!
