WHY don't wolves perform in circuses?

Wolves only feel comfortable and safe when they are in a pack.

A wolf pack is a highly socialized group, where each animal has its own social role. A solitary animal does not survive in the wild, it is chased out of all places, so the wolf's life depends on the pack.

And it is impossible to train a pack of wolves in a circus.
