For instance, what can you do with the Cocker Spaniels in these shows besides show them?

Cockers are field dogs. Most of them also have field champion finishes.

Toys, on the other hand....

[and the horse you rode in on]

Cockers are field dogs. Most of them also have field champion finishes.

Some rarte cockers are suitable for both dog shows and field trials. There are other seperate field trials bloodlines that aren't nearly as pretty. Most cockers are good only for peeing on the floor whenever they get excited.
