Pets in vrchat that follow the character

I once saw that someone can create a pet that follows a model. The pet has an animation of inactivity and walking.
So, does this really work in vrchat? If so, maybe someone knows tutorials or something else that could help me create something like this.
Oh, I would be very happy if I could make pets…

That would be the Walking Pet Sheep. You need to be a $5 patron of VRLabs to access.
