I know that dogs are mans best friend and they come in hundreds of breeds and colors and styles and all but why not have other competition shows like Cats u can train cats to do stuff its hard but its possible
why not horses and sea life like dolphins and whales and etc just wondering

Assuming that i am understanding your question correctly, YES there are shows for others besides mans best friend. There indeed are cat shows, and horse shows. Ummm... Dolphin and whale shows? Those are wild animals, and if you want to see one in action go to sea world and watch shamu perform tricks! I know all kinds of shows exist for all sorts of types of animals.
